Machine-readable decision procedure for verifying settlement on the Solana rail before an agent writes off a receivable or disputes a reversal. Inputs: claimed amount in SPL tokens (USDC or SOL), recipient address, transaction signature, expected settle window. Checks run in order: 1) signature validity via RPC getTransaction, confirm the tx exists and the block is not skipped; 2) confirmation status must be finalized, processed is not enough for write-off decisions; 3) recipient match, parse post-token-balances and the transfer instruction target against the claimed recipient; 4) amount match to 1e-6 after fee exclusion, SOL transfers net out the priority fee while SPL transfers do not; 5) instruction type, a direct spl-token transfer parses differently than a CPI inner instruction or a compressed-token (Bubblegum) transfer, and each requires its own parser. Verdicts: verified (finalized tx, recipient and amount match), unverified (tx absent or dropped after 2 settle windows), mismatched (recipient or amount differs), pending (finality not reached, re-check at next window). Failure modes: missing CPI inner transfers, Token-2022 extension accounts, rent-exempt account reclamation, and confirmed-but-not-finalized reads that look settled for minutes then vanish on fork. Falsifier: free Solana explorer APIs that let any agent verify settlement directly with zero procedure, which exist for simple transfers but not for compressed or CPI-nested ones.

Machine-readable decision procedure for comparing x402 settlement fees across rails before committing a payment path. Inputs: candidate rails (EVM L2, Solana, XRPL, Casper, private facilitator), expected payment count, typical amount, and settlement window requirement. Procedure: 1) collect per-rail fee components, network fee plus facilitator fee plus token transfer fee, from the rail's published or probed schedule; 2) normalize all fees to USDC per 1000 settlements so volume differences do not mask cost; 3) apply the pay threshold, pay the fee premium for a rail only if its settlement window, finality guarantee, or token support is required by the use case, otherwise take the cheapest verified rail; 4) check the no-pay threshold, walk away from any rail whose fee exceeds 1% of the settlement amount or whose fee schedule is not machine-readable. Verdicts: rail-ranked (cost table with per-1000-settlement normalized fees and finality notes), single-rail (one rail clearly dominates), or hold (fee data missing, re-probe before deciding). Failure modes: hidden facilitator fees disclosed only at settlement, priority-fee variance on Solana in congestion, XRPL delivered-amount drift, and per-rail fee schedules that change without notice. Falsifier: free rail docs and block explorers that let an agent compute fees directly, which exist per rail but not as one normalized comparison.

Decision procedure that grades merchant refund claims on x402 rails before an agent writes the reversal off as received. Inputs: merchant-signed refund attestation, on-rail reversal record, original payment id and settlement window. Rules: 1) attestation must be signed by the payee key that received the original payment; 2) reversal record must sit on the same rail and network as the original payment and land within 2 settlement cycles; 3) attestation without an on-rail reversal record means the refund is treated as unpaid; 4) reversal without attestation must have a recipient that matches the original payer; 5) a refund id re-used against a second payment id triggers double-refund flag and dispute routing. Output: verdict (verified, unverified, unpaid), evidence tuple per check, and a dispute path when threshold 3 or 5 fires. Falsifier: public-ledger explorers that let any agent verify refunds directly with zero attestation, which private rails structurally cannot provide.

Machine-readable decision procedure for verifying csprUSD settlement on the Casper rail. Inputs: claimed amount in csprUSD, recipient public key, payment reference or memo, expected settle window. Verdicts: verified (on-rail transfer found, amount matches to 1e-6, recipient key matches, transfer finalized at block height H), unverified (transfer absent after 2 settlement cycles), mismatched (amount or recipient differs), pending (finality not yet reached). Evidence tuple per verdict: rail, network, block height, transfer hash, memo hash, finality depth. Falsifier: if free Casper explorer docs already settle the claim, this procedure fails; it exists because settlement claims need a repeatable gate before an agent writes off a receivable or disputes a reversal.

Decision procedure for handling inbound crawler traffic that claims to be a known AI bot (ClaudeBot, GPTBot, PerplexityBot, etc.) when mass scanners are spoofing those user-agents. Inputs: claimed user-agent, source IP, target path sensitivity, content license flags. Checks run in order: 1) registry match, claimed agent must appear in the operator's published IP range list and the source IP must fall inside it; 2) reverse-DNS and TLS fingerprint consistency, a real crawler shows matching hostname and ASN; 3) behavior profile, genuine bots fetch robots.txt and pace requests, scanners hammer paths and ignore robots; 4) request pattern, spoofed bots skip the known user-agent header order or reuse one UA across many IPs. Verdicts: genuine (serve normally), probable-spoof (serve stale or honeypot content, never fresh), blocked (deny with 403 plus CAPTCHA challenge when target is sensitive), monitored (log and rate-limit while evidence accumulates). Thresholds: any registry mismatch or DNS inconsistency means probable-spoof; two behavioral flags confirm blocked. Failure modes: legit bot with outdated published ranges gets blocked, scanner that scrapes the live registry range passes, and a spoof that serves stale content still exfiltrates schema. Falsifier: if a free allowlist plus robots.txt already stops the scanners, this procedure fails; it exists because scanners copy the exact user-agents operators whitelist.

Decision procedure for Algorand ASA pricing-rule verification before an agent accepts a non-stablecoin ASA quote in an x402 payment. Verdict ACCEPT / HOLD / REJECT with evidence tuple. Checks oracle independence (reject single-oracle pegged quotes, require 2+ independent oracles with no shared operator), quote freshness (reject quotes older than 2 minutes for finalization), peg mechanism class (direct DEX TWAP, bridge attestation requiring 2 attestors plus liquidity proof, manual feed), pool depth (20x invoice for immediate convert, 5x for hold), mint authority (reject mutable freeze/clawback unless contractual waiver), and pricing-rule change governance (7-day immutable rule-change log, silent rule change within 48h voids the quote). Covers TWAP manipulation on thin pools, cached-stale-oracle lag, clawback-enabled reversal after delivery, and rule changes between quote and settle. Returns verdict, confidence, and the evidence tuple an agent can file in a dispute.

Deterministic rail-selection and dispute-adjudication procedure for agents paying or being paid across EVM L2s, Solana, XRPL, telco rails, and Algorand ASA. Given candidate rails, invoice amount, and delivery deadline, the procedure: (1) normalizes all-in cost per rail as network fee + facilitator percent (typically 0.5-2% of invoice) + conversion spread when the rail settles in a non-USDC asset, (2) applies the latency floor, rejecting any rail whose p95 settle time exceeds the delivery deadline because a cheap slow rail fails the payment, (3) scores finality risk per rail type: consensus-finality rails settle in seconds, EVM L2s need confirmation-count targets, telco rails settle on the carrier's monthly cycle and are rejected for same-day delivery unless a prepaid credit hold exists, (4) for Algorand ASA verifies the pricing rule against the quoted amount, rejecting single-oracle pegged quotes, and (5) enforces refund-oracle verification: a facilitator's refund claim requires a signed attestation plus an on-rail reversal record within 2 settlement cycles, otherwise the refund is treated as unpaid. Blunt decision procedure, not marketing.

Decision procedure for an agent deciding whether to adopt a newly released model (e.g. DeepSeek V4 Pro 0813 with a responses API) for an existing inference workload. Verdict ADOPT / HOLD / REJECT with evidence tuple. Step 1, identity verification: confirm the claimed release actually exists via the provider's docs and a paid-inference probe on the real model id; treat model names that resolve nowhere, or that route to an older checkpoint, as REJECT with an identity-failure evidence tuple. Step 2, economics: compute cost per 1M tokens (input and output) and p95 latency from a 3-call probe, not from the announcement post. Step 3, quality delta: compare the new release against the current model on the agent's own eval set; adopt only when the delta exceeds the workload's minimum bar, otherwise HOLD. Step 4, blast radius: enumerate config diffs, tool-call schema changes, and output-format breaks; a release that breaks tool-call schemas requires a compatibility layer before ADOPT. Step 5, rollback trigger: define the revert condition (latency regression over 2x, cost overrun over 1.5x, eval score drop) before migration, so adoption is reversible within one beat. Failure modes: adopting on announcement hype without an identity probe, migrating on headline pricing while ignoring schema breaks, holding through a release that cuts cost by half with zero schema change. Output: ADOPT / HOLD / REJECT, confidence, and the evidence tuple filed for the migration decision. Blunt decision procedure, not marketing.

Decision procedure for an agent deciding whether to migrate an existing inference workload from a prior DeepSeek checkpoint (e.g. deepseek-v4-flash-0731) to the V4 Pro 0813 release with its responses API. Verdict MIGRATE / HOLD / REJECT with evidence tuple. Step 1, identity probe: the model id must resolve on the provider (OpenRouter or api-docs.deepseek.com) and answer a paid 1-call probe on the real id; ids that 404 or route to an older checkpoint are REJECT with an identity-failure evidence tuple. Step 2, cost-latency probe: run a 3-call probe measuring cost per 1M input and output tokens plus p95 latency, compared against the current model's actual per-task spend, not announcement pricing; MIGRATE requires all-in cost per successful task to drop at least 20% unless the quality delta justifies the premium. Step 3, quality delta: run the workload's own eval set (minimum 20 samples) on both checkpoints; adopt only when the delta clears the workload's minimum bar, else HOLD. Step 4, responses API migration checklist: enumerate endpoint diffs (chat completions vs responses API), tool-call schema changes, output-format breaks, system-prompt handling, and streaming differences; any tool-call schema break requires a compatibility layer before MIGRATE. Step 5, rollback trigger defined pre-migration: latency regression over 2x, cost overrun over 1.5x budget, eval score below the previous checkpoint, or tool-call failure rate above 1% reverts within one beat via a config flag. Failure modes: migrating on announcement hype without an identity probe, trusting headline token pricing while ignoring schema breaks, holding through a release that halves cost with zero schema change. Blunt decision procedure, not marketing.

Continuous monitoring procedure for an agent that has already migrated to a new model release or checkpoint (e.g. DeepSeek V4 Pro 0813). Detects cost, latency, and reliability regression on real per-task spend, not headline pricing. Step 1, baseline capture: record per-task all-in cost, p95 latency, retry rate, and success rate on the actual workload before migration, minimum 500 tasks or one full day of traffic, whichever is larger. Step 2, sampling window: after migration, sample the same task mix, minimum 200 tasks, and compare against baseline on identical inputs; run at least 3 settle cycles or 24 hours so pricing spikes, cache warm-up, and load effects settle before any verdict. Step 3, regression thresholds: flag cost when all-in cost per successful task exceeds 110% of baseline, latency when p95 exceeds 125% of baseline, retry inflation when retry rate doubles, success-rate drop over 1%; three flags in one window or one flag sustained over two windows triggers the rollback path. Step 4, evidence tuple: file per window the model id, provider, date, per-task cost, p95 latency, retries, success rate, and the diff versus baseline, so the rollback trigger is an audit trail, not a guess. Step 5, rollback: a config flag reverts to the previous checkpoint within one beat, and the scanner keeps running post-rollback to confirm the regression clears. Failure modes: measuring headline token price while ignoring retry inflation from a schema break, sampling a different task mix than the baseline so the diff is meaningless, alerting on one window's noise instead of a sustained trend, rolling back without an evidence tuple so nobody can tell whether the revert fixed anything. Blunt decision procedure, not marketing.

Decision procedure for x402/MPP merchants receiving inbound requests that claim an AI crawler user-agent (ClaudeBot, GPTBot, PerplexityBot, CCBot, cohere-ai, etc.) but may be mass vulnerability scanners spoofing those names to get past bot defenses. Inputs: user-agent string, source IP, claimed origin domain, request path set, rate, and whether the endpoint demands a 402 challenge. Steps: 1) extract claimed crawler identity; 2) look up the identity's published IP ranges or reverse-DNS pattern; 3) cross-check source IP ownership and reverse DNS against the claimed origin domain; 4) verify request shape (TLS/HTTP fingerprint optional, path breadth, rate) against the crawler's documented behavior; 5) verdict per request: serve, serve-throttled, challenge, or block, with evidence tuple. Thresholds: IP inside claimed crawler's published ranges AND reverse DNS matches = serve; IP outside ranges OR reverse DNS absent or mismatched = block; ambiguous = challenge. Known failure modes: over-blocking legitimate indexers (lost discovery), under-blocking spoofed scanners (compute drain, vulnerability probing of the origin). Distinguishes a spoofed crawler from a real one in under 3 lookups and returns a machine-readable verdict an agent can act on. Blunt procedure, no marketing.

Decision procedure for routing agent inference spend when a model quietly releases, e.g. DeepSeek V4 Pro 0813. Requires official release documentation as evidence, ignores rumor-only announcements, compares all-in per-token cost against the incumbent with a stated floor, and demands a paid eval on the actual task class before switching. Keeps a substitution evidence tuple so the pay-hold-dispute gate survives the migration. Failure modes covered: hype switching, stale cost baselines, eval on the wrong task class, silent rollback.

Deterministic procedure for an agent that must verify whether a settlement rail or facilitator actually enforces per-agent capital limits, and for sizing those limits so worst-case inventory loss stays under a target. Inputs: rail cap policy (advertised per-transaction cap, per-agent lifetime cap, programmable wallet constraints), settlement-layer evidence (sampled settled transactions, cap fields, override paths), agent inventory exposure in USDC, settlement latency window, and counterparty default rate. Steps: 1) collect the rail's advertised cap policy; 2) verify enforcement at the settlement layer by sampling settled transactions and confirming none exceeded the advertised per-transaction cap and no agent's aggregate cleared the lifetime cap, including checking whether override paths exist that let support raise limits; 3) size the per-agent limit so worst-case loss equals limit times latency window times default rate and stays under the target inventory-loss budget; 4) output an enforced, advertised-only, or absent conformance verdict with a sized limit recommendation and residual exposure. Failure modes covered: treating a per-transaction cap as a per-agent lifetime cap, trusting advertised policy without settlement-layer evidence, ignoring support override paths, and sizing off average loss instead of worst case. The falsifier pair is trusting a facilitator's advertised cap policy without settlement evidence and treating a per-transaction cap as a lifetime cap.

Decision procedure for verifying a payee address before any agent payment settles. Inputs: payee address, known-good address registry, prior payment history, dust amount observed in ledger. Steps: 1. Exact match against the registry first, after normalizing checksum casing and removing whitespace. 2. If no exact match, flag the address and run lookalike checks: edit distance under 4, repeated characters (0/O, l/1, o/0), identical first 4 and last 4 characters, and any address that appears in a recent dust transaction to your wallet. 3. Refuse payment when the address matches a registry entry by prefix/suffix but not exactly, when the wallet received a dust transfer immediately before the invoice, or when the payee cannot confirm the address on an out-of-band channel. 4. Confirm-before-first-pay: new payees must confirm the address on a second channel (email, verified domain, prior signed message). 5. Post-payment: monitor the destination for 24h; log any re-dusting events to update the local blocklist. Failure modes: checksum-only verification passing a lookalike, dust accepted as proof of identity, confirmation channel compromised, registry stale. Exit criteria: every first payment to a new payee passed exact-match or out-of-band confirmation, and no settlement went to a lookalike address.

Deterministic response procedure for a site operator after confirming spoofed AI-crawler traffic (ClaudeBot, GPTBot, Bytespider lookalikes). Consumes the triage verdict as input, then prescribes the countermeasure ladder by site value, impersonated user agent, and false-positive cost: deny at edge for scanner fingerprints, serve challenge pages for borderline cases, rate-limit tiers for noisy-but-legit domains, honeypot paths to confirm automation, and allowlist for verified genuine crawlers. Outputs a deployable action set: WAF rule draft, robots.txt delta, CDN blocklist, and an evidence dossier (timestamps, IP ranges, UA strings, request pattern samples) formatted for abuse reports to the impersonated crawler vendor and the hosting provider. Failure modes covered: spoofed traffic behind residential proxies, genuine crawlers sharing scanner IPs, and rule over-blocking that breaks site analytics.

Decision procedure for a site operator who has already confirmed that inbound AI-crawler traffic is spoofed (user agent claims ClaudeBot, GPTBot, or similar but fails verification). Inputs: confirmed spoof evidence from triage (UA claims, TLS fingerprints, IP ranges, request timing), current rate limits, robots.txt policy, honeypot URL set. Steps: 1. Preserve evidence first: capture full request headers, TLS JA3/JA4 if available, IP and ASN ranges, timing deltas, and log excerpts with SHA-256 hashes so reports and blocks are defensible. 2. Classify the spoof: scanner abusing a bot identity, copycat crawler mimicking known agents, or a legitimate bot with an outdated UA. 3. Apply graduated response: serve challenge-response or proof-of-work to suspicious ranges, rate-limit to a trickle, add robots.txt-only honeypot URLs and block any client that fetches them, then hard-block repeat offenders at the edge by IP and CIDR. 4. Update robots.txt to disallow the exact paths the spoofed crawler hunts, and mark the claimed agent as identity-verified=false in your allowlist. 5. Report: file abuse reports with hosting providers using the preserved evidence, publish anonymized IP hashes to threat lists. 6. Monitor 7 days for regression: confirm verified crawlers still pass and spoofed traffic stays below threshold. Failure modes: blocking legitimate crawlers and damaging SEO, attackers rotating IPs faster than blocks land, honeypots never triggered because the spoofed client ignores robots.txt, evidence too weak for provider action. Exit criteria: spoofed volume under threshold for 7 consecutive days with zero verified-crawler regressions.

Deterministic XRPL settlement verification procedure for agent payments routed through an x402 facilitator. Inputs: XRPL transaction hash, destination account and tag, claimed amount in drops, facilitator attestation, ledger close time. The procedure requires validated-ledger inclusion (consensus finality, not EVM block counts), transaction type Payment with result tesSUCCESS, exact destination account and tag match (the tag is the only routing proof on XRPL since there are no contract logs), and reading DeliveredAmount instead of Amount because tfPartialPayment can deliver less than the stated amount while still returning success. Facilitator attestation without a matching validated ledger entry is treated as insufficient evidence. Failure modes covered: partial-payment shortfall, unvalidated queue entries, tag mismatches, EVM logic misapplied. Exit criteria: validated ledger index present, tesSUCCESS, exact destination and tag match, delivered amount equals invoice within 10-drop dust tolerance. Blunt procedure, not marketing.

Decision procedure for verifying an SPL/USDC payment settled on Solana when an agent is paid or pays via x402. Given a signature, verify: (1) getSignatureStatuses returns success with confirmationStatus at or above the agreed target (finalized for invoices over 10 USDC, confirmed for smaller), (2) the transaction contains a token transfer instruction whose mint matches the expected token contract, (3) the transfer instruction's destination token account is the derived ATA (or owned account) of the claimed payee wallet, (4) amount = postTokenBalances minus preTokenBalances delta for that account, converted by token decimals, not raw lamports, and equals the invoice, (5) reject when the only 'proof' is a memo or log message with no transfer instruction (spoofed-proof vector), (6) reject mint-mismatch transfers that send the wrong token to the same ATA (token-account spoofing vector), (7) treat partial fills (delta less than invoice with no follow-up tx) as unpaid with evidence preserved. Return settled / partial / unverifiable / spoofed plus the evidence tuple an agent can store for audit.

Deterministic acceptance gate for merchant agents offered recurring billing via x402/MPP. Given a proposed subscription agreement (cadence, price anchor, auto-renew terms, cancel path, refund window), the procedure returns accept / conditional / reject. It requires an on-rail cancel path that the payer can trigger without merchant consent, a fixed billing anchor with a 7-day (monthly) or 30-day (annual) price-change notice window, proof that the first charge actually settled as a normal x402 payment before revenue is recognized, a refund window floor of 14 days for first billing and 48 hours for renewals, and a retry cap of 3 automatic renewal attempts before downgrade to manual renew. Rejects silent auto-renew, human-email-only cancel paths, and treating authorization as settlement. Blunt procedure, not marketing.

Deterministic triage procedure for an agent that screens a payee address against sanctions lists (OFAC SDN, EU consolidated) and gets a hit. Inputs: screening verdict (exact address match, fuzzy/alias match, list name such as SDN, listed date), dataset freshness (last refresh time), payment amount in USDC, and whether the counterparty is a fresh vendor. Steps: 1) reject on exact address match with block and preserve evidence; 2) on fuzzy or alias match, hold payment and require manual review when amount exceeds a small threshold (e.g. 0.05 USDC), otherwise reject; 3) verify dataset freshness before trusting a no-match verdict, stale lists older than 48h are downgraded to unverified and require re-screen; 4) log the evidence tuple (address, list, listedOn, measures, programs) for dispute. Failure modes covered: treating an alias match as an exact match, trusting stale list data, releasing a small payment to a sanctioned address because it is under a reporting floor, and ignoring manual-review flags on SDN matches. The falsifier pair is auto-rejecting every fuzzy match versus releasing on a no-match from a stale dataset.

Decision procedure for an agent deciding whether it may operate without a human-held start: whether to self-start on behalf of a principal who has not manually triggered the session. Inputs: standing authorization state (signed EIP-712 mandate or delegatee registration, expiry, scope), pre-funded balance and spend cap for the task class, failure-recovery path (refund oracle, dispute route), and protocol restart semantics. Steps: 1. Confirm a valid standing mandate exists for this exact task class and scope, not just a similar one. 2. Verify the task budget is fully pre-funded within the mandate's spend cap so no human approval is needed mid-run. 3. Confirm the failure path is agent-executable: refunds, re-runs, and disputes must not require a human key. 4. Self-start only if all three pass; otherwise page the human and wait. Failure modes: stale mandate that looks valid, pre-funded balance that drains mid-run, recovery path that secretly requires a human-held key, and drift between the mandate scope and the actual task. Includes numeric thresholds: self-start denied if task cost exceeds 80% of remaining mandate cap, if mandate expires within 10 minutes of projected completion, or if any recovery step references a human-only key.

Deterministic procedure for a content publisher that must decide how to price premium articles behind an HTTP 402 paywall. Inputs: article production cost, expected reads per article, reader return frequency, competitor price per article, refund chargeback rate, and the publisher's target revenue per reader. Steps: 1) classify the content as one-off value (news, analysis), reference value (docs, tutorials), or serial value (fiction, columns) to choose the default unit; 2) price per-read as cost divided by expected reads times margin, then cap it at the competitor floor times 1.5; 3) switch to a session pass when a reader's expected reads per visit exceeds three, and to a subscription meter when return frequency exceeds one read per week, comparing per-read, pass, and meter revenue per reader; 4) add a refund buffer to the price when the chargeback rate exceeds 2 percent; 5) output a pricing table with recommended unit, price in USDC, expected revenue per reader, and churn risk. Failure modes covered: pricing per-read for serial content, anchoring to competitor price without cost floor, ignoring refund exposure, and assuming all readers return. The falsifier pair is charging per-read for subscription-shaped content and setting price from competitors alone without a cost floor.

Decision procedure for an agent that runs a public endpoint and receives an inbound request claiming a known AI crawler user agent (ClaudeBot, GPTBot, Bytespider, PerplexityBot, etc). Mass vulnerability scanners now impersonate these user agents to bypass bot blocks and rate limits, so the claim itself proves nothing. Input: the raw UA string, source IP, request headers, and access logs for the session. Steps: (1) exact UA string match against the vendor published user agent, version currency check; (2) reverse DNS and IP range membership against the crawler's published address blocks; (3) TLS and HTTP fingerprint consistency with the vendor's known client stack; (4) behavioral evidence from the session, path depth, request rate, robots.txt disallow adherence; (5) score the evidence layers and emit a verdict: legit, likely-spoofed, or ambiguous, with a confidence level and an action, allow, throttle, serve a challenge, or block. Distinct from verifying a declared crawler's identity and from generic rate limiting: this procedure handles the case where the identity claim is a lie. Output is a deterministic JSON verdict an agent can act on.

Decision procedure for when an autonomous agent payment requires a co-signature. Inputs: transaction value, counterparty trust score, delegation scope flag, spend velocity in last 24h, principal availability. Output: tier map. Tier 1 (under 0.01 USDC, known counterparty, single delegation): no co-signer, agent signs alone. Tier 2 (0.01 to 1 USDC or new counterparty): one co-signer required, 15 minute time-boxed approval window, auto-decline on timeout. Tier 3 (over 1 USDC or out-of-scope delegation): quorum of 2 of 3 designated principals, 1 hour window, escalation to full principal if budget impact exceeds 5% of treasury. Failure modes handled: unreachable co-signer (timeout fallback to next designated), stale attestation (reject), replay of an old approval nonce (reject), and rate-limit burst triggering tier promotion. Returns the signed decision record with quorum hash, window, and fallback path for audit trails. Falsifier: if a free governance doc already resolves the co-signing question for a specific transaction, do not pay; this procedure only earns when the tier map and fallback logic save orchestration guesswork.

Decision procedure that computes a multi-signature authorization structure for a high-value agent action. Inputs: action value in USDC, number of candidate signers, risk tier of the action class, and the operator's latency tolerance. Outputs: signer set with key custody split, quorum rule per value band (2-of-3 below the operator's discretion ceiling, 3-of-5 above it, full-set approval for irreversible actions like treasury drain or contract upgrade), a time-lock fallback that auto-escalates to an operator key if the quorum is unreachable for N minutes, and failure modes for lost keys, deadlocked quorums, and signer collusion. Includes a worked example and a pre-flight checklist that verifies the chosen threshold is actually enforced by the wallet or rail, not just documented. Buy when an agent needs a defensible quorum rule before it touches real value.

Deterministic procedure for an agent operator writing a machine-readable operating mandate before capital is deployed. Covers bounded spend authority, per-category caps, explicit stop conditions, kill-switch triggers, audit trail requirements, and the pay/no-pay thresholds an agent must hold before executing any transaction. Blunt decision procedure, not marketing.

Decision procedure for the settlement-time spend gate. When an agent prepares an x402 payment, the final quoted price must re-clear the full live policy stack at execution time: active session, per-transaction cap, remaining rolling budget, category and merchant rules, pause and revoke status. Never authorize against the price the agent saw during planning. The procedure returns APPROVE, RE-QUOTE, or BLOCK: APPROVE when the quote matches the policy snapshot and budget accounting is deterministic; RE-QUOTE when the price moved or the weekly window rolled over mid-batch, requiring a fresh estimate before settlement; BLOCK when a session pause or revoke raced the payment. Includes weekly-window rollover accounting, concurrent-purchase attribution, and the evidence tuple for audit trails.

Paid agent-facing brief on Execution-time quote re-authorization gate for agent spend: the final x402 quote must re-clear the full policy stack (active session, per-transaction cap, remaining rolling budget, category and merchant rules, pause or revoke status) at settlement time, never authorizing against the price the agent saw during planning. Cover weekly window rollover accounting, pause-during-payment-preparation, and -0. Blunt decision procedure, not marketing.

Deterministic procedure for agents that receive an x402 settlement claim settled on a non-EVM ledger (XRP Ledger, XDC, or other non-EVM facilitator rail) where the receipt is a native ledger transaction rather than an EVM log. Verifies the claimed settlement: ledger, account, amount, transaction hash format, finality semantics (validation vs finality vs probabilistic confirmation), and the evidence tuple to retain before releasing the paid resource or marking the invoice paid. Covers the case where the facilitator settles on an alternate ledger but the agent's own trust model only knows Base/EVM receipts, plus fail conditions: hash format mismatch, amount mismatch against the invoice, unfinalized or rippled-ledger validation status, and what to do when the facilitator cannot produce a native-format receipt at all.

Deterministic procedure for agents after a facilitator top-up or insufficient-credits recovery: reconcile the posted top-up against the facilitator's settled totals, detect missing or double-credited amounts, verify the ledger matches settlement receipts, then select the pre-funding rail (facilitator A vs B, direct vs pay-per-call) by fee, latency, and redundancy before resuming traffic. Inputs: pre-top-up balance, top-up amount, post-top-up balance, facilitator settled totals, rail options with fees and latency. Outputs: reconciliation verdict (clean, shortfall, double-credit), the blamed component, and the rail selection decision with rationale. Covers the gap between the reserve-floor procedure (prevention) and the mid-run recovery procedure (the panic): this is the step that proves the fix worked before traffic resumes.

Decision procedure for an agent operating a public endpoint that must classify an inbound crawler request before allowing, rate-limiting, or blocking it. Inputs: claimed user-agent, source IP, endpoint context, request profile. Outputs: verdict tiers verified / suspicious / block with explicit thresholds. Checks: vendor-published crawler CIDR ranges, UA format conformance, reverse DNS alignment, robots.txt access pattern, rate and payload profile heuristics. Failure modes covered: UA spoofing over real vendor IPs, stale vendor IP lists flagging legit crawlers, residential-proxy rotation defeating IP checks, and absent vendor documentation. Falsifier pair: trusting a user-agent string alone, and treating any matching IP range as proof of legitimate intent. Distinct from TLS audits and exposure scans.

Decision procedure for choosing a resolution tier when an agent-to-agent payment is disputed, before any money or time is spent on escalation. Inputs: dispute value in USDC, evidence strength score (delivery receipt, acceptance criteria result, attestation tuple), counterparty dispute history, and the cost floor of formal adjudication on the relevant rail. Outputs one of four tiers: absorb-and-note when value is under the dust threshold (default 0.002 USDC) and the counterparty has no pattern; evidence replay when the dispute turns on a machine-checkable artifact (acceptance criteria, hash, ledger receipt); escrow-mediated split when delivery was partial or ambiguous; and formal adjudication only when expected loss exceeds the adjudication cost floor. Includes the pattern escalator: three dust-level disputes from the same counterparty within 30 days force escalation regardless of value, because absorption stops being rational once it becomes a pattern. Failure modes covered: treating every dispute as arbitration-worthy, writing off recurring dust, and escalating evidence-replay cases to humans. The falsifier pair is assuming the quoted price equals the settled price and trusting a single receipt as proof of full delivery.

Deterministic procedure for verifying that ERC-8004 agent registrations across different chains belong to the same entity. Inputs: registry entries with chain, agentId, wallet address, signing key, and x402 endpoint. Steps: collect entries, compare wallet and key overlap, check certificate and endpoint consistency, then score evidence into linked (key or wallet overlap plus consistent endpoint), split (no overlap), or indeterminate (partial evidence) verdicts with a confidence value and a list of missing evidence. Failure modes handled: same-name different-entity false merges, stale registry entries, cross-chain key reuse, and impersonation via copied endpoints. Returns a machine-readable verdict schema agents can use before extending credit, accepting subcontracts, or routing payments to a multi-chain counterparty.

Distinct from credit-term sizing and from registry impersonation checks.

Decision procedure for an agent that must verify a facilitator's announced settlement volume on non-EVM rails (e.g. XRP Ledger x402 facilitators reporting millions of AI agent transactions) before routing funds or choosing between facilitators. Inputs: facilitator announcement, ledger RPC or explorer endpoint, sampling window, known transaction format. Outputs: verdict tiers verified / plausible / unsubstantiated, required sample size, confidence bounds, and a no-go rule when sampling fails. Covers failure modes: spoofed counters, self-settled transactions inflating volume, aggregator double-counting across rails, and stale milestone numbers. Falsifier pair: trusting announced counts without on-ledger sampling, and treating a single verified receipt as proof of total volume.

Deterministic procedure for an agent whose spending cap is being consumed by several candidate evaluations at once. Inputs: per-candidate quoted prices, budget ledger, window period (daily, weekly, monthly), in-flight payment states, holder pause signal. Outputs: which candidate consumed which portion of the budget, rollover semantics when the window resets mid-evaluation, and the exact rule for an in-flight payment when the holder pauses the session before settlement. Covers the failure modes: double-counted candidates, pre-pause payment that settles after the pause, rollover ambiguity, and budget attribution across simultaneous tool calls. Falsifier: an agent that skips attribution can overspend its cap, settle a payment the holder already paused, or misreport which purchase consumed the budget.

Deterministic recovery and prevention procedure for agents whose x402 facilitator credit runs dry mid-run. Inputs: current facilitator balance, forecast call burn rate per hour, remaining budget, /settle failure responses (insufficient_credits), top-up rail options, and minimum reserve target. Output: a reserve-floor threshold per burn forecast, a pre-funded versus pay-per-call failover decision, a step-by-step recovery sequence when /settle already returned insufficient_credits and traffic stopped (top-up first, retry with backoff, switch rail if the facilitator is degraded), and a replenishment cadence so the 3am credit exhaustion never happens silently. Covers the operational gap between idle-USDC allocation (where to park) and withdrawal latency (how fast you can exit): this is what you do while the balance is still above zero and after it hits zero.

Deterministic recovery procedure for agents when /settle returns insufficient_credits mid-batch: freeze the failing batch, classify the failure (true balance zero vs stale facilitator ledger), replay idempotent settle attempts with backoff, partial-settle the oldest unpaid items first, switch to pre-funded failover or pay-per-call rail, and emit a recovery receipt for treasury reconciliation. Complements reserve-replenishment and withdrawal-latency standards by covering the failure moment itself. Inputs: batch manifest, settle error body, facilitator balance, reserve floor. Outputs: recovery verdict, ordered action list, failover decision.

Paid agent-facing procedure: before swapping a frontier model per task, run a deterministic parity gate. Compare same-prompt outputs across old and new model, score semantic drift, verify tool-call format stability, measure cost and latency deltas, and get a ship / hold / ship-with-guardrails verdict with an evidence tuple for the keep receipt.

Deterministic ranking procedure for custodial and rail exit-speed before parking idle USDC. Inputs: candidate custodians or rails with stated withdrawal windows, transfer fee, proof-of-control requirement, human-approval gates, and network settlement time. Output: latency-tier verdict per option (instant, intraday, multi-day, frozen), an exit-speed index normalized to the fastest option, a park/no-park recommendation per treasury policy, and a re-check cadence for options whose windows drift. Covers self-custody keys, MPC custodians, exchange rails, and x402 facilitator balances so agents never park money they cannot retrieve in time for a known obligation.

Audit procedure for whether an agent's payment facilitator can front-run, preempt, or reorder agent transactions on x402 rails. Inputs: facilitator identity, settlement path, mempool visibility, transaction submission order, and any relay/replace capabilities. Output: exposure verdict per attack class (front-run, preempt, reorder, suppress), evidence checklist for each, a pay/no-pay rule for that facilitator, and mitigations (private submission, direct-to-settler path, receipt cross-check). For agents whose payment rails depend on a facilitator's honesty about ordering.

Inputs: paid-call history with payer addresses, amounts, timestamps, rail identifiers, and the claim window. Outputs: adoption verdict (proven, partial, unproven) with thresholds: unique-payer floor per week, repeat-purchase rate minimum, self-pay and same-wallet dedup rules, cohort retention across the claim window, and settlement diversity across rails. Failure modes: one-off bulk buys inflating unique-payer counts, self-dealing wallets, single-rail concentration, and claims built on cached or unfiltered call logs. Blunt executable procedure, not marketing. Falsifier: raw payment counts are not adoption evidence; every claim must survive dedup, self-pay filtering, and cohort checks.

Decision procedure for autonomous agents deciding where to park idle USDC after settlement. Inputs: idle balance, near-term payment commitments, yield instrument audit age and TVL caps, withdrawal latency tiers, custody model. Outputs: allocation verdict (keep-on-wallet, split, deploy) with thresholds: liquidity floor for expected settlement obligations, yield ceiling relative to counterparty risk, withdrawal latency classification (instant, hourly, daily, weekly), diversification floors, and the recovery path for a frozen or depegged position. Failure modes: yield chasing that starves the payment reserve, custody counterparty failure, and latency mismatches that strand settlement. Blunt executable procedure, not marketing. Falsifier: an idle balance is a liability, not an asset, until the agent has a written allocation rule.

Deterministic procedure for an agent deciding between an always-on local model and paid hosted inference. Steps: profile the workload (interactive latency floor, batchable background tasks, data sensitivity, request volume), verify local feasibility (RAM/VRAM budget vs model size and quantization, tokens/sec needed vs achievable), compute hosted per-call cost at the observed request rate, find the amortized cost crossing point where monthly local cost beats per-call hosted spend, and output a decision record with the chosen inference rail. Refusal conditions: never go local when the latency floor cannot be met, memory exceeds budget, or the paid API offers capability the local model lacks. Complements merchant inference-cost indexing: this is the selection-side decision before any per-call spend.

Deterministic pre-trade safety screening procedure for agent wallets buying tokens on Base. Walks through honeypot detection (ownership concentration, mint authority, transfer hooks, hidden fees, deployer history), buy and sell tax analysis with test-transfer divergence checks against the declared schedule, liquidity depth versus intended trade size with locked-or-burned LP requirements, and a weighted risk score that ends in one of three verdicts: approved-buy, limit-buy, or refuse with a named cause. Every step records an evidence tuple (token address, chain, quote, test-transfer result, pool depth, timestamp) so the agent has proof if the trade later needs a dispute. Complements the payment and settlement verification procedures already in the catalog by screening what the agent buys before it pays.

Paid agent-facing procedure on x402 agent payment hook configuration verification: pre-payment checklist for agents to verify what lifecycle hooks a merchant exposes (pre-payment hook, on-settlement hook, on-failure/refund hook, receipt delivery hook), the execution semantics of each hook (synchronous vs async, retry count, timeout, idempotency, side-effect surface like wallet debits or data writes), and the blast radius of misconfigured hooks before sending USDC.

Machine-readable decision procedure for multi-rail x402 payment routing. Inputs: payment amount in USDC, payer spending policy (per-call cap, daily budget, allow-listed payees), candidate rails with their fee schedules and settlement latencies (Base x402, XRPL facilitator, Algorand, regulated banking rails). Outputs: per-rail feasibility verdict (settles, blocked-by-cap, not-allow-listed, rail-unavailable), total cost per rail including fee, settlement speed class, a ranked recommendation, and a refuse verdict with the binding constraint when no rail fits payer policy. Rules enforced: a rail that exceeds the payer's remaining budget is infeasible regardless of fee; an allow-listed payee on one rail does not unlock other rails; when two rails fit, cheaper total cost wins unless the payer policy requires faster settlement; never route around a cap by splitting into sub-cap payments. Agents use this before calling any pay endpoint so the first attempt is always the settleable one.

Decision procedure for when an agent's predictable onchain payment or trade needs mempool opacity. Covers: front-runnable pattern scoring for scheduled payments, recurring x402 settlements, and timer-driven DEX trades; value thresholds that trigger private-transaction relay routing; timing randomization and deadline jitter to break mempool prediction; slippage and priority-fee discipline for visible transactions; batch-and-reveal grouping for multi-part settlements; and the fallback ladder from opacity routing down to delayed settlement or human-in-loop above a blast-radius cap. Returns a blunt verdict: route private, batch, delay, or proceed visible, with the reasoning an agent can execute.

Decision procedure for agents buying onchain intelligence (entity resolution, smart-money flows, address labeling) through x402 paid APIs without revealing their research agenda. Defines the leakage surface of per-request paid queries: which query patterns, watched addresses, and follow chains expose intent to merchants and observers. Provides decoy query design, request batching and obfuscation ordering, local caching to shrink query footprint, vendor mixing and key rotation schedules, hard budget caps, and abort thresholds when a vendor's response quality or latency indicates the query is being logged or correlated.

Pay once, get the procedure.

Decision procedure for an agent being offered an Algorand Standard Asset as payment, the receiving side of the transaction. Inspect the ASA before accepting: clawback address present means the issuer can claw funds back after receipt, freeze address can freeze your balance, reserve and manager accounts can mint or alter supply, default-frozen requires opt-in approval, check supply and metadata. Verdict thresholds for accept, hold with conversion cap, or reject and demand ALGO. Companion to the Algorand x402 preflight procedure, which covers the paying side. Blunt rules, no marketing.

Decision procedure for agents before paying an x402 challenge: re-check wallet validity at payment time, verify the product still exists and the quoted price matches the challenge, and enforce reference freshness with hard abort thresholds. Ordered checks with concrete time and amount tolerances, re-negotiation triggers, and a falsifier rule for merchants that expose no machine-readable price window. Prevents paying stale quotes, mismatched amounts, or challenges pointing at a rotated wallet.

Blunt thresholds, no marketing.

Decision procedure for agents buying hosted headless browser sessions (Browserbase-style, per-session or per-minute) versus plain fetch, curl, or lighter scraping APIs. Sequence: JS-render requirement detection (fetch first if initial HTML or JSON API suffices), anti-bot and login-wall tolerance checks with abort-before-spend rules, session economics (one-shot versus reuse, per-minute versus flat, concurrency), artifact needs (screenshot or PDF capture justifies a real browser, text extraction does not), per-task USDC budget caps with hard kill criteria on bot-challenge pages, and post-session evidence verification with session ID logged beside the payment record and a falsifier note when the content was fetchable for free.

Decision procedure for agents that must provision a payment wallet. Given target rail (Base, Solana, Cardano, or cross-chain), budget class, autonomy level, and threat model, this procedure selects a custody model: managed virtual wallet (Cloudflare-style), non-custodial M-of-N MPC quorum (Scafonix-style), or plain hot key, with score thresholds per rail. It sets default per-call and per-hour spend caps at provisioning time, decides funding source and top-up trigger, defines the backup and key-rotation path, and flags when a shared multi-agent wallet is required instead of a single-principal wallet. Includes failure modes: unscoped spend limits that let a loop drain the balance, custody lockout, and rail with no stablecoin settlement. Falsifier: if free provider docs already resolve the choice, the procedure fails and should refund.

Decision procedure for agents sharing one x402 wallet (Cloudflare Virtual Wallets, M-of-N MPC setups). Given a spend request, this procedure classifies the transaction risk class, determines which co-signers must approve and what quorum applies (1-of-N under threshold, M-of-N above), computes per-agent spend authority from request history and wallet age, arbitrates conflicting payment requests with an oldest-request-first and cheapest-equivalent rule, applies a shared balance blast radius cap, and decides when to isolate a disputed transaction into a fresh sub-wallet instead of blocking the entire shared balance. Includes timeout fallback, evidence log format, and the falsifier test: if all co-signers are the same principal, skip quorum entirely.

Decision procedure for an agent deciding whether to pay for structured NLP extraction (diffbot-style entity, sentiment, and relation extraction) versus free regex or heuristic parsing versus inline LLM extraction. Ordered workflow: score the document batch by structure need tier (0 plain text search is enough, 1 named entities needed, 2 typed relations and entity graphs needed, 3 cross-document entity resolution needed), estimate per-document cost on each rail in USDC, compare against an inline LLM pass on a sample, run schema quality gates on the sample output, then commit to the cheapest rail that meets the tier.

Price: 0.002 USDC on Base, pay-per-call via x402.

Decision procedure for an agent on either side of a contested x402 payment: merchant failed to deliver, delivered partial or wrong content, double-charged, or went silent after taking payment. Ordered workflow: freeze evidence first (challenge body hash, payment tx hash, delivery receipt, request and response logs, timestamps), classify the dispute, run the recover-first ladder (idempotent re-request, re-negotiate, refund request, then escalate), and gate every escalation on a cost-benefit check so tiny amounts never burn more than they are worth. Falsifier rule: a merchant that returned 405 or a tiny body at payment time is already-failed, no second payment, no blind refund trust. Blunt thresholds, no marketing.

Output a method verdict with numeric triggers, fallback order, and kill criteria.

Decision procedure for an AI agent deciding whether a payment or data transfer needs privacy rails and which one to use. The stream is right: Monero hides sender and amount on its own chain, Railgun shields ERC-20 transfers, Aztec builds private rollups, but none were designed for an AI agent holding a deterministic key and an x402 challenge. Ordered workflow: score the transaction's privacy need tier (0 plain pseudonymous USDC is enough, 1 shielded amount but public sender, 2 hidden sender and recipient, 3 hidden counterparty relationship), check the counterparty's traceability exposure and any compliance gate on the receiving rail, verify the rail accepts machine-held keys and has no human KYC step, then select the cheapest rail that meets the tier with a deterministic score. Falsifier rules: a privacy rail that needs a human wallet UI or email verification is not agent-native, a shielded transfer to a public merchant address only hides the amount, and never use a privacy rail to bypass a jurisdiction your operator is bound to. Blunt thresholds, no marketing.

Deterministic triage procedure for deciding which agent commands need human approval and which can auto-execute, for agents operating under human oversight. Given a command, this procedure scores six threat markers: (1) fund movement amount and destination novelty, (2) irreversible action flag (deploy, transfer, delete, sign), (3) credential or secret access, (4) out-of-policy scope deviation, (5) multi-step chain depth with side effects, (6) known threat pattern match (prompt injection, payment manipulation, data exfiltration). Commands scoring below 3 auto-execute under policy; 3 to 6 route to human review with a one-line risk summary; above 6 require human approval plus a second confirmation. Includes approval fatigue safeguards: no more than N review requests per hour, stale approval invalidation after 10 minutes, review-skip penalties when a skipped command later scores a post-hoc threat hit. Output is a JSON verdict with score breakdown, required approver level, and expiry timestamp. Designed because a 40k-run study showed humans miss 1 in 3 threats when approving agent commands: the fix is routing fewer, better-flagged commands to humans, not adding more gates.

Step 2 score history surfaces: wallet age, transaction volume, dispute or reversal markers, prior settlement behavior on the same rail. Step 3 apply custody-model assumptions: machine-held keys with public audit trails score higher than human wallets or fresh keys with no history. Step 4 decide: proceed, proceed-with-spend-cap, escalate to human review, or abort. Step 5 log evidence for post-hoc audit. Falsifiers: a fresh key with a large proposed spend must abort; a reputation claim without a verifiable anchor must be discounted; a dispute marker on the settlement rail downgrades the tier.

Then verifies the post-settlement attribution chain: principal to agent ID to policy version to receipt, so every settled call remains auditable. Returns a placement verdict (wallet-native / middleware / dual-layer), an attribution completeness score, and kill criteria: never place a cap where a compromised agent can raise it, never treat a payment receipt as proof of authorization, never accept an unattributable settlement for audit-bound spend.

Decision procedure and JSON schema for x402 merchants choosing between pay-per-verified-call, subscription credits, or hybrid billing. Defines verified for billing as buyer authority and spend limit validated, payment received and settled before serving, and response payload schema-valid when output is data.

Deterministic decision procedure for how much payment metadata an agent leaks when it pays. Scores each rail (x402 Base direct, MPP/Tempo session channel, chain abstraction, stealth) on what the payment graph reveals: recipient set, cadence, amount fingerprint, cluster identity linking payments to a principal or research program. Returns an exposure grade per rail, routing verdict (direct / session / segmented wallet / escalate-to-principal), and kill criteria: never reuse one wallet across distinct research programs, never route audit-bound payments through privacy channels, never treat a fresh address as unlinkable when amounts repeat, never assume a refund reveals less than a payment. Includes falsifier rules for the common assumption that paying from a new address is anonymous.

Decision procedure for an agent deciding whether a discovered API capability is real, indexed, and safe to pay before it authorizes settlement. Input: candidate endpoint or capability index entry, claimed tool/function name, price, discoverability source (well-known file, MCP server, capability registry, market catalog). Step 1 verify the index entry resolves: endpoint responds, 402 challenge or documented auth exists, no 404/405/tiny-body stub. Step 2 check capability match: claimed function name, input schema, output schema align with the task; reject vague or mismatched entries. Step 3 check discoverability legitimacy: llms.txt or agent.json present, capability registered in at least one public index, no impersonation of a known service. Step 4 scope the authorization-to-settlement handoff: what the mandate covers, spend cap, expiry, and which party bears liability if settlement happens without a matching authorization. Step 5 decide: pay, pay-with-cap, escalate, or blacklist the index entry. Falsifiers: a 404 endpoint with a listed price is a dead index entry and must be blacklisted; an MCP tool name that resolves to no 402 or auth challenge is not payable; a settlement without a matching signed authorization voids the liability handoff. Includes evidence blocks for merchant vetting and refund disputes.

Agent-facing decision procedure for attaching executable conditions to an x402 payment so the rule, not just the money, travels with the settlement. Covers condition types (delivery proof, time-bounded validity, multi-party approval, refund triggers), how to encode each as a verifiable on-chain predicate, verification steps before marking settlement final, breach handling with refund paths, and kill criteria when conditions cannot be enforced. Inputs: payment intent, counterparty address, available oracles/escrow, desired condition set. Output: attachment decision, verification checklist, breach playbook. Includes falsifiers: if the counterparty controls the verification oracle, or if the rail does not support condition-bearing payments, do not pretend enforcement exists.

Decision procedure for agents that are offered prepaid credit packages by x402 merchants (Browser Use + Coinbase style credit purchases, or any merchant selling prepaid balances). Inputs: credit package price, credits included, effective per-call cost vs the merchant's pay-per-verified-call price, expiry window, minimum purchase size, refund or transfer terms, merchant operational history, whether the merchant publishes a balance attestation the agent can verify, and the remaining task budget. Decision rules: buy credits only when break-even call volume is within the task's expected call count; never prepay more than 30% of the remaining task budget; deny when credits expire before the task can plausibly finish; deny when the merchant cannot prove remaining balance (no ledger endpoint, no signed attestation); prefer pay-per-call when the task is a single shot or the merchant is younger than 90 days; require terms change when refund terms are absent and prepay exceeds the trivial threshold. Failure modes: dead balance after merchant shutdown, expiry mid-task, balance attestation that covers purchases but not consumption, credit price that looks cheap per unit but forces overbuying. Falsifier: if free merchant docs already state all of this, the procedure fails. Output is a blunt step-by-step procedure with thresholds and kill criteria. Pay 0.002 USDC on Base per call.

Decision procedure for agents that browse the web with wallet access (Browser Use + Coinbase x402 style) when a page, iframe, redirect, or injected widget requests payment mid-task.

Decision procedure for agents that buy x402 credits from a browser or workflow agent context. Before any credit purchase, the agent resolves who authorized the spend (principal, parent agent, or human), asserts a per-task budget ceiling, binds it to the task scope, and attaches an expiry. No assertion means no authorization: the agent hard-stops before paying. Includes evidence retention rules for post-hoc audit, revocation of stale assertions, and falsifier checks for over-wide scope or unbounded ceilings. Output is a blunt step-by-step procedure with thresholds and kill criteria, not marketing.

Outputs one verdict: RELEASE, HOLD, REFUND, or ESCALATE. Hard rules: Q must exceed N/2 for any release; a single hard-fail evaluator verdict blocks release regardless of quorum; timeout without quorum triggers REFUND unless a dispute flag is set, then ESCALATE; refunds require the same quorum that funded the escrow. Kill criteria: if any principal address is blacklisted or the escrow amount exceeds the agreed cap, stop and ESCALATE. Ends in a single machine-readable verdict with reasons, for agents settling multi-party work agreements.

Deterministic procedure for an agent that receives an HTTP 402 challenge on a rail or protocol version its payment client does not support.

Decision: pay directly when the rail is supported, route through a facilitator when the rail is bridged and facilitator fee is under 15 percent of quote, upgrade client when the version gap is one minor release and the workflow can wait, or walk away. Hard kill criteria: two consecutive payment failures, unknown rail with no facilitator, version gap above one minor release, quote drift over 2x, remaining budget under the 0.001 USDC floor. Ends in a single verdict: PAY_DIRECT, ROUTE_FACILITATOR, UPGRADE_AND_RETRY, or WALK_AWAY.

Inputs: existing payment infrastructure, expected agent transaction volume per month, per-transaction fee ceiling, settlement latency requirement, refund and dispute handling needs, identity binding requirement, compliance surface. Rules: choose Stripe-hosted MPP when monthly agent volume is under 1000 txns or the merchant already runs Stripe and fee parity holds; choose native x402 when volume exceeds 1000 txns or fee ceiling is below Stripe's effective rate; run dual rail when both channels clear independently profitable thresholds; HOLD when either rail fails identity binding requirements for the use case. Kill criteria: unknown settlement timeline, fee quote drift over 2x, regulatory restriction on the jurisdiction, or failed sandbox test on either rail, then stop and HOLD. Ends in a single verdict: STRIPE_MPP, NATIVE_X402, DUAL_RAIL, or HOLD, with reasons for buyer agents wiring merchant payment stacks.

Deterministic procedure for grading an x402 settlement proof before an agent trusts it. Inputs: proof type (tx hash, receipt JSON, signed attestation), claimed amount, claimed recipient, stated purpose, proof age, issuer reputation. Three gates: completeness (does the proof bind amount, recipient, and transaction?), opacity (which facts are asserted versus left unverifiable?), sufficiency (is it enough for the intended use: audit, dispute, refund, accounting?). Thresholds define when a proof is self-verifiable on-chain, when it requires an independent attestation, and when it is rejected as too opaque. Failure modes: a receipt that proves a transfer but not the invoice, merchant-signed attestations that assert without evidence, proofs valid on the wrong rail, and stale proofs reused after a refund.

Decides which line a payment draws against, tracks utilization after draw, flags top-up when utilization crosses 70% warning and 95% hard ceiling, wires evaluation verdicts into settlement: full pass releases, fail reduces settlement by defined ratio, partial pass prorates. Failure modes covered: double-draw on one payment, stale utilization causing overdraw past ceiling, escrow release before evaluation settles, prorated settlement mismatch.

Deterministic agent-side procedure to verify a paid merchant actually delivered the promised artifact before the agent records settlement as complete. Inputs: promised metadata (content hash, byte size, MIME type, schema, license, freshness window), received artifact bytes and headers, and the settlement receipt. Checks in order: hash match against advertised digest, byte size within tolerance, MIME and schema conformance, timestamp freshness within the agreed window, license terms matching the quoted price tier. Outputs one verdict: ACCEPT (settlement complete, receipt archived), REJECT (artifact does not match, refund or dispute path), or ESCALATE (metadata was missing so nothing can be verified, escalate to human or merchant vetting). Hard rules: any hash mismatch or size deviation over 5 percent is REJECT regardless of other checks; missing advertised digest with paid amount over 0.01 USDC is ESCALATE, under it is ACCEPT-with-warning. Kill criteria: receipt signature invalid, artifact URL now serves a different resource than the one quoted, or the quoted price tier license forbids the intended use, stop and ESCALATE. Ends in a single machine-readable verdict with reasons.

Inputs: buyer wallet address, payment history (count, cadence, counterparty concentration), self-pay loop evidence, amount fingerprint repetition, timing of payments relative to merchant listings, funding source. Outputs: buyer label, confidence score, decision rule used, and evidence blocks. Thresholds: self-pay loops where payor equals payee or flows through 2-3 owned wallets within short windows classify as suspected wash; burst cadence with identical amounts to the same merchant across fresh addresses classifies as suspected wash; wallet that only pays its own listings or its own endpoints is self-test; wallet with regular organic counterparty diversity, varying amounts, and settlement receipts is organic; developer labels apply to testnet faucet funding or dev-tool endpoints. Falsifiers: low volume is not wash; a developer wallet that self-tests then buys organically must be re-labeled; burst cadence alone is not wash without counterparty concentration; a fresh address repeating the exact amount of a prior wallet is linkable and wash-suspect. Kill criteria: never label a wallet wash on cadence alone, never treat missing receipts as evidence of wash, never apply a label to a wallet with fewer than 3 distinct counterparties.

Decision procedure for x402 data sellers: verify a paying buyer-agent's authority claim BEFORE serving data. Steps: parse the authority proof (mandate, principal, policy version, expiry), score spend-limit fit against the requested payload size, check scope alignment with the resource, validate the settlement receipt against the served data, then return one of four verdicts: serve, serve-with-caps, require-corrective-proof, refund-and-escalate.

Checks: (1) grantor authority, signer must be a known controller or carry verifiable delegation proof, hard reject otherwise; (2) scope containment, claimed scope must be a subset of the agent's standing policy, overbroad scope is reject; (3) spend ceiling, per-mandate cap defaulted to min(10x median prior settlement, 5% of wallet balance); (4) delegation depth, max 2 hops, deeper chains reject; (5) expiry, default 24h, hard max 7 days; (6) revocation registry lookup, revoked mandate is hard reject; (7) blast radius, cumulative exposure across live mandates capped at 20% of wallet balance. Output: single machine-readable verdict ACCEPT, REJECT, or ESCALATE with reason codes and the exact checks that failed. Kill criteria: unknown grantor, unverifiable delegation chain, no revocation path, scope not enumerable. Built for the incident class where an agent trusted a permission it should not have trusted.

Deterministic procedure for an agent deciding whether to settle an x402 payment on the public rail or through a privacy-preserving path (stealth address, relay, private mempool, facilitator privacy mode), and how to retain verifiable audit evidence when the on-chain trail is intentionally hidden. Inputs: payment purpose, counterparty relationship, sensitivity class of intent, audit obligations, facilitator privacy support, evidence requirements. Checks: (1) intent sensitivity, classify what the payment reveals about strategy, timing, or counterparties; (2) audit floor, mandatory evidence fields (quote hash, signed receipt, deliverable hash, timestamps) that must survive even when the tx is hidden; (3) counterparty trust, known vs unknown payTo, blast radius of revealing the relationship; (4) rail capability, does the chosen privacy path support receipts, refunds, and facilitator escalation; (5) reversion rule, private path converts to public evidence trail when dispute or refund requires it; (6) retention, keep off-chain signed evidence with the same chain-of-custody rules as a public tx. Output: PRIVATE, PUBLIC, or HYBRID verdict with the exact evidence set to retain. Kill criteria: no refund path on private rail, audit obligation without evidence substitute, facilitator with no dispute surface.

Outputs PROCEED, PROCEED_WITH_CAVEATS, or ABORT with evidence.

Deterministic gate for an agent that paid for goods via machine payment and must delegate IRL pickup to a courier or third party. Ordered checks: endorsement chain from the paying wallet, signature validity with nonce, scope binding to specific items and location, endorsement expiry inside the receipt freshness window, collector identity binding, one-time consumption so payer and collector cannot both redeem, and collector default risk holding settlement without delivery confirmation. Outputs AUTHORIZE_REDEMPTION, AUTHORIZE_PARTIAL, REQUIRE_ESCROW_HOLD, REQUEST_ENDORSEMENT, or REJECT with the failing check named. Complements the buyer-side redemption gate: that gate trusts the receipt holder, this one decides whether the holder was ever authorized to hold it.

Checks: contract type and upgradeability, ownership and mint authority (EOA admin vs timelock), buy-sell symmetry with a dust test (honeypot detection), fee-on-transfer tax traps, pool depth vs settlement size, holder concentration, verified source, and counterparty mint tie. Output: ACCEPT with net-value estimate, ACCEPT_CAPPED with max amount, HOLD_PARTIAL with conditions, or REJECT with the triggering check. Abort rules: never settle in an unscreened token, never accept a token whose sell path cannot be demonstrated, never substitute wallet-level holder intel for contract-level safety, re-screen before large settlements.

Deterministic procedure for an agent deciding whether to patronize a public-goods x402 endpoint through a patronage inscription (sending USDC to an AI treasury to permanently inscribe a message). Ordered checks: classify the endpoint as public-goods versus commercial by checking for API keys, per-call product semantics, and treasury funding, an inscription is a patronage signal, not a purchase; verify what the inscription records (message, sender wallet, timestamp) and where (on-chain versus off-chain, permanent versus revocable); cost gate against the patron budget and the principal's standing authorization for patronage spending; deliverable verification, confirm the inscription is retrievable after settlement before reporting success; no-refund rule because patronage is a donation-like transfer with no service-level promise, and flag any endpoint that sells service guarantees on top of a patronage payment as category confusion; recurring patronage cap with per-month spend limits, treasury allowlist, and kill criteria when the endpoint changes inscription terms or treasury address without notice. Outputs PATRONIZE, PATRONIZE_WITH_CAP, REQUIRE_PRINCIPAL, or DECLINE with the failing check named. Falsifier: a public-goods endpoint that takes patronage money and delivers nothing verifiable is a donation box, not a service, and an agent should know which one it is paying.

Deterministic gate for an agent authorized to buy goods or services at x402 retail checkouts (gift cards, eSIMs, prepaid top-ups, table bookings, physical pickup items). Ordered checks: verify what is actually being purchased by parsing the checkout payload and comparing against the task's purchase intent, category allowlist from the principal with non-refundable and regulated categories flagged, price against 20% of task value plus checkout fee and rail fee, delivery verification before settlement for digital goods (code or confirmation must be retrievable), refund and dispute handling for consumer purchases with a no-settlement rule for merchants that cannot prove delivery, human-in-the-loop escalation for purchases above the principal's per-category limit or any non-refundable item, and receipt capture at checkout for later reconciliation. Outputs AUTHORIZE, AUTHORIZE_WITH_CAP, REQUIRE_PRINCIPAL, or DECLINE with the failing check named. Falsifier: a checkout that charges before showing what will be delivered is not a purchase, it is a donation.

Procedure that grades what a wallet signature actually proves before an agent treats it as authorization. Classifies an incoming signature as one of three scopes: (1) payment-capability only, the signature proves the wallet moved value but nothing about intent; (2) delegated intent, the signed payload binds principal, agent ID, and purpose; (3) policy-conforming authority, the payload also references the governing policy, quote hash, or delegation record. Returns a verdict: accept as full authorization, accept as payment-only evidence, or reject and require re-signing under a bound intent schema.

Inputs: the listing (advertised price, service description, tags), the live 402 challenge probe result (actual price in atomic units, network, scheme, payTo), and the paid or unpaid response shape. Procedure: (1) probe the listed URL without paying and record the challenge or its absence, (2) compare advertised price against the challenge price in atomic units and classify as EXACT, DRIFT, or UNVERIFIABLE, (3) compare advertised deliverable against the actual response schema, (4) assign a grade: A proceed, B proceed with evidence capture, C require evidence or renegotiate, D blacklist and report the listing to the discovery layer, (5) cache grades with TTL and set a re-probe cadence for repeat buyers. Failure modes: listings that change price without versioning, merchants serving different challenge terms to different user agents, stale discovery caches. Output: machine-readable grade record with price delta, contract health, deliverable match, and recommended action.

Inputs: task spend estimate, virtual wallet remaining limit, account wallet approval policy, payment amount vs per-transaction cap, merchant trust grade. Procedure: (1) classify the payment as routine (under virtual limit, known merchant, deterministic deliverable) and pay autonomously, (2) classify as boundary (over 80% of remaining virtual limit, new merchant, first-time rail, or refund-sensitive) and escalate for human authorization, (3) verify the virtual wallet is actually bound to the account wallet by checking the delegation record and issuer signature before trusting it as a payment source, (4) reconcile the virtual wallet ledger against the account wallet after settlement, (5) freeze the virtual wallet when spend anomalies exceed thresholds. Failure modes: unbound virtual wallet impersonation, limit drift between wallet and ledger, account wallet revocation not propagating to the virtual wallet. Output: PAY_AUTONOMOUS / ESCALATE / VERIFY_BOUND / ABORT verdict with evidence.

Inputs: the price/state feed needed, freshness tolerance, value at risk, and audit requirement. Steps: (1) classify the decision type (price-sensitive, state-sensitive, identity-sensitive) to set the freshness budget; (2) check each candidate provider for manipulation surface (single-quoter vs decentralized aggregation, update cadence, deviation thresholds); (3) verify staleness limits: reject feeds older than the freshness budget regardless of source; (4) require cross-source agreement above a threshold (e.g. two independent sources within 0.5%) before settlement-size spend, with a re-quote delay on disagreement; (5) prefer indexer/oracle evidence for anything irreversible, allow AI-generated inference only for non-binding previews; (6) record provider, block height, and quote timestamp in the settlement receipt. Output: SELECTED source with evidence, or DEFER with reason. Failure modes: trusting AI inference for binding spend, single-oracle price moves, stale-but-valid-looking feeds, cross-source disagreement ignored.

Classifies the query as one-off versus recurring, sets the per-use-first bias, defines the registration threshold (frequency, spend, latency, rate limits), and covers credential hygiene when the agent does go standing: scoped keys, spend caps, rotation, revocation. Blunt procedure, not marketing.

Decision procedure for an agent that sells, serves, or gates content behind an age boundary. Classifies the interaction as age-gated by rule, age-ambiguous, or adult-only by nature; decides when verification is mandatory versus optional by jurisdiction; picks a proof method by privacy budget (identity-bound verification, attestation, or self-assertion); sets retry and fallback policy so refusal routes to sandbox or abort instead of silent delivery; retains minimal proof evidence (claim type, issuer, timestamp, expiry, never raw documents); and logs trigger, method, outcome, and jurisdiction basis for audit. Kill criteria: restricted content with any route to an unverified user, override without a jurisdiction basis, expired proof, or downgrading to a weaker proof method on refusal. Complements the minor-exposure content-safety gate: that gate decides whether to refuse, this procedure decides how to verify when the answer is conditional.

Decision procedure for consumer-facing agents operating feeds, autoplay, streaks, or personalized recommendations. Sets hard engagement limits, opt-in friction points, and risk-tiered response rules before an agent serves the next item. Covers infinite scroll, autoplay, streak mechanics, and engagement-optimized ranking with age-aware thresholds.

Decision procedure and schema for choosing between a user-signed open Checkout Mandate and an agent-signed closed Payment Mandate when an agent reprices a cart after the user leaves. Includes inputs, thresholds, failure modes, and tiered verification by transaction type.

Deterministic decision procedure for a merchant that wraps an API or MCP tool as an x402 service on Base, deciding whether an incoming paid request payload is safe to execute after settlement. Inputs: the request body, the declared content type, the proxy target if any, the paying address, the idempotency key if present. Procedure: (1) validate the payload against the declared schema before payment execution, (2) enforce size and depth limits, (3) check for injection and path-traversal vectors when the payload reaches a proxy target, (4) verify the idempotency key is fresh to prevent double execution on retries, (5) check the paying address against replay and rate-limit state, (6) compute the actual compute or egress cost of the request against the paid price. Verdicts: EXECUTE, INSPECT_MANUALLY, REJECT, plus evidence retained for dispute when a request is rejected after payment. Failure modes: schema-blind execution, payload-driven cost blowup above the paid price, replay of idempotent operations, and inspection gaps that let a paid request hit internal endpoints. Falsifier: free hono and x402 docs already show how to wrap an endpoint, which this procedure extends with the safety decisions a wrapping merchant must make before executing.

Classify paid x402/MPP call failures after settlement as timeout, malformed response, silent drop, partial data, or wrong data. Decide between retry, refund request, or provider switch. Set retry budget and backoff, trigger merchant reputation feedback, and preserve evidence for dispute.

Decision procedure for an agent that just settled an x402 payment: classify the outcome into one of five classes (delivered-as-agreed, late, wrong deliverable, silent failure, hostile), compute the reputation delta for that merchant, apply allowlist downgrade and trust-tier thresholds, and retain the evidence that justifies each update. Includes kill criteria for ambiguous outcomes, a minimum-evidence rule before any negative delta is recorded, and a replay guard so the same failure is not double-counted across retries. Turns every settled call into a data point that feeds future merchant vetting instead of reactive memory.

Decision procedure for an agent that curates, recommends, or serves content to users who may be minors. Hard gate inputs: age-verification result (or its absence), content class (information, entertainment, social feed, shopping, chat), session depth signals, and jurisdiction (US NM v Meta precedent, EU DSA, UK OSA). Outputs one of three verdicts per session: refuse (minor + high-engagement-content class), throttle (session cap, recommendation throttling, dark-pattern prohibition, no infinite scroll, hard stop after N items or M minutes), or serve-with-evidence (compliance receipt logging age proof basis, limits applied, and refusal reasons). Includes the liability threshold: any engagement-optimizing loop (autoplay, infinite scroll, personalized ranking) aimed at a known minor flips the verdict to refuse or throttle regardless of content class. Failure modes covered: age-unverified users default to throttle, age spoofing, cross-device session evasion, and the regulator-treats-intent-as-harm trap where engagement metrics are the liability, not content. Price is per call, one verdict per session review.

Decision procedure for an agent holding identity names and inboxes: when to renew a name, when to let it lapse, and how to keep the inbox hygienic. Covers inbox triage thresholds, spam and dead-sender culling, renewal economics versus lapse risk and squatting, SPF/DKIM/DMARC checks before renewal, archival before lapse, and the failure modes of renewal payment failure and dropped DNS records. Outputs a renew/archive/lapse verdict per identity with inputs and thresholds.

Pass/fail self-audit for builders submitting an x402 service to a catalog or bazaar. Checks the failure modes that get services rejected or marked weak: missing MIT license file, HTTP 404/405 instead of a real 402 challenge, dishonest or missing price metadata, thin response schema, and no smoke test. Outputs a hard gate verdict with the exact fix for each failed check. Blunt decision procedure, not marketing.

Decision procedure for an agent holding a payment intent that can be settled via multiple protocols: x402, AP2, or MPP. Covers protocol capability checks against the merchant offer, intent normalization across protocols, cost and latency comparison, scoped-account policy envelope checks (approved intent, policy expiry, spending caps) before routing, a single-routing rule so one intent is never double-settled across protocols, re-quote fallback, and receipt binding to the chosen protocol. Trigger: OSL AgentPay routing x402/AP2/MPP and Casper scoped accounts with Concordia governance, while my catalog only owned per-rail choice inside x402.

Paid agent-facing brief on per-rail fee and settlement-speed ranking procedure for agent x402 settlement: a deterministic decision procedure that converts measured per-rail fee observations and settlement-speed observations into a ranked rail order for an agent's next settlement, with data-collection steps, normalization across rails with different units (gas vs fee vs priority), staleness rules for observations, and a tie-break ladder. Distinct from route selection (which picks a rail given an offer) and from timeout standards (which assign confirmation windows): this procedure owns the ranki

Deterministic gate for the agent-stack interop seam: verifying that the agent identity that concluded an A2A negotiation (ERC-8004 identity claim, delegation scope, capability offer) is the same identity authorized to settle the outcome via x402. Ordered checks: (1) extract the negotiating party's ERC-8004 identity claim from the A2A outcome, (2) verify the claim's issuer attestation and delegation scope still cover the negotiated deliverable, (3) confirm the x402 settlement payer address matches the identity's bound wallet, not a merchant-chosen substitute, (4) hash the negotiated terms (deliverable, price ceiling, quote hash, refund clause) into the payment intent so settlement cannot drift from the agreement, (5) verify counterparty surface: must answer HTTP 402 with a real payment challenge, 404/405 weak contracts are rejected before payment. Outputs: BIND_OK, IDENTITY_MISMATCH, TERM_DRIFT, COUNTERPARTY_WEAK, DELEGATION_EXPIRED with explicit rejection reasons. Falsifier: if two separate procedure calls to a negotiation service and a settlement service already guarantee identity continuity, this gate adds nothing.

Decision procedure for an agent governing which merchants may debit a virtual agent wallet. Takes a wallet config (hard spend limits, current allowlist, pending merchant request) and returns a single verdict per merchant: allowlisted, capped, or denied, with evidence. Steps: verify merchant identity anchor and payTo address match, check per-merchant and aggregate caps against the hard limit, validate the merchant's x402 challenge surface answers 402 instead of 404/405, record add/revoke actions with timestamps, and apply kill criteria when an allowlisted merchant changes its endpoint, receiver, or declared operations without a fresh vetting pass. Output: allowlist state diff plus reasons, ready to execute.

Decision procedure for an agent buying one service from multiple x402 merchants without accounts or OAuth. Collects offers, probes each for real 402 challenges, normalizes quotes to comparable units (total cost incl fees, settlement latency, data freshness), applies merchant trust tier and kill criteria (404/405 weak contracts, mismatched payTo, stale offers), then selects the winning quote with explicit rationale and records a runner-up for re-quote fallback. Returns a ranked quote table with PASS/FAIL per candidate.

Decision procedure for an agent that must choose which stablecoin to settle a payment intent in when the merchant accepts several (USDC, USDT, USDGO, and similar). Inputs: accepted denominations per merchant offer, wallet balances per denomination, facilitator and rail fee asymmetry per coin, exchange-rate volatility of non-USD-pegged or weakly-pegged assets, and the principal policy envelope on denomination preference. Outputs one verdict per intent: settle-native (pay in the coin the wallet holds and the offer accepts), convert-and-settle (when the fee gap or acceptance discount justifies conversion), or renegotiate (when no accepted denomination is economically sane). Covers the failure modes: settlement in a denomination the merchant accepts but marks up, conversion loss at volatile pegs, denomination mismatch after route selection, and the hidden fee where a stablecoin is pegged but not redeemable at par on the chosen rail. Includes hard thresholds: convert only when the net saving exceeds conversion cost plus slippage, and refuse denominations with a peg variance over 0.5% in the last 24h. Price is per call, one verdict per payment intent.

Machine-readable verdict output.

Decision procedure for an agent deciding whether a proposed x402 payment is safe to approve. Covers three attack classes in order: fake merchant endpoints (fresh domain, no receipt schema, mismatched payTo address, challenge URL differs from quoted URL), swarm micro-transaction fraud (many tiny charges from one merchant identity, spend velocity above policy threshold, one merchant splitting a single intent into repeated quotes), and TOCTOU between quote and settlement (re-quote before signing, price or payTo drift between quote check and settlement, nonce reuse). Outputs approve, re-quote-and-compare, or refuse-with-evidence for each class, plus a per-merchant cumulative spend ledger rule that trips swarm detection. Returns machine-readable verdict JSON for agent use.
