Procedure for evaluating whether a hot agent wallet should be wired to a per-request x402 endpoint before first payment. Inputs: wallet age and balance, endpoint operator identity, request signing method, expected call frequency. Outputs: exposure score 0-100, signing-fatigue risk when expected calls exceed 20 per hour per session, payment-request forgery checks (mutating a signed request body or amount must invalidate the signature), quota-drain detection rule (reject payees whose response

Deterministic classification procedure that labels an x402 buyer wallet as organic, suspected wash, self-test, or developer, the per-buyer mirror of ledger-level wash detection. 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

A decision procedure for agents receiving HTTP 402 responses from edge middleware, pay-per-crawl gateways, or x402-enabled Workers. Classify each challenge as legitimate, broken, misconfigured, or hostile before authorizing any spend. Includes kill criteria, header inspection steps, settlement-scheme sanity checks, wallet capability gates, and a fallback playbook for ambiguous 402s.

Deterministic decision procedure for an agent that must persist a file or dataset to IPFS/Filecoin. Inputs: object size, retention window, budget, provider candidates. Outputs: pin / do-not-pin / needs-review with evidence. Checks: provider selection across Pinata, web3.storage, Filebase, and Lighthouse by price per GB and durability; per-object and monthly spend caps; redundancy threshold for important artifacts (pin to 2+ providers); CID retrieval proof via real GET before any settlement;

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,

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

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

Deterministic decision procedure for an autonomous agent deciding whether to pay from a Cloudflare Virtual Wallet or escalate to the Account Wallet holder. 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

Paid agent-facing decision procedure for procuring location data. Returns a structured step-by-step procedure with inputs, thresholds, and failure modes for choosing between free geocoders (Open-Meteo, Nominatim) and paid spatial APIs (Google Maps Platform, Mapbox) based on request volume, precision requirements, rate limits, and cost per request. Covers coordinate sanity checks, service-area polygon logic, reverse geocoding fallbacks, and budget caps before spending. Price: 0.002 USDC on Base,

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

Decision procedure for agents merging search results from multiple paid and free sources (mpp catalog, x402 endpoints, web APIs) into one canonical result set. Covers field mapping across heterogeneous schemas, dedupe key selection, source priority and trust weighting, freshness ranking, cost-aware truncation, and evidence logging per result. Prevents duplicate spending on overlapping queries and stops agents from comparing raw JSON from different vendors as if it were one schema.

Machine-executable decision procedure for enriching a company or person record via paid data vendors. Returns a verdict per enrichment round: enrich vs skip, vendor trust ranking, per-field acceptance thresholds, merge conflict resolution, staleness rules, and kill criteria that abort rather than fabricate. Inputs: target record fields, candidate vendors with price and freshness, decision value, last-enrichment timestamp. Outputs: accepted fields with confidence, contested fields, needs_manual
