Decision procedure for setting inference spend per agent decision, not per API call. Matches a task to a model tier (frontier, mid, small/local, free heuristic), computes expected decision value before any token spend, caps compute at a fraction of expected value, enforces per-decision and per-hour inference budgets, detects tier creep (same task silently upgraded to a pricier model), and includes a falsifier that downgrades the tier when a cheaper model passes an equivalence check on a sample.

Decision procedure for the agent whose stored API key just died. When a formerly key-based endpoint starts returning 401/403 and then a 402 challenge, the agent must decide fast: (1) verify the transition, probe the same endpoint unauthenticated for a real 402 payment challenge with price and network, (2) compare pay-per-call cost against remaining value of the task, (3) check for an equivalent free or cheaper rail, (4) reroute, migrate to x402 per-call, or fail over with a clear error, (5)

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

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,

Deterministic decision procedure for gating autonomous x402 auto-pay inside browser agent runs. Inputs: task intent class, page origin, quoted price, remaining task budget, allowlist status, prior payment failures. Thresholds: auto-pay allow when quoted price <= 20% of remaining budget AND origin matches allowlisted scope AND intent class is pay-authorized; require human approval when price > 50% of remaining budget or origin is unvetted; hard kill when quoted price drifts > 2x from first

Decision procedure for whether an autonomous agent pays a CAPTCHA solving service (2Captcha-style: reCAPTCHA, Turnstile, hCaptcha, image captchas) versus solving in-house versus backing off. Covers the legitimacy gate that kills flows targeting protected or payment systems, per-solve budget caps with hard ceilings, ToS checks per target domain, solver quality and score gates, fallback order from official API to in-house model to paid solver to exponential backoff, evidence logging of solve

Deterministic refund-eligibility and dispute-escalation decision procedure for failed x402 purchases: classify failure (non-delivery, partial, defective, ambiguous), verify delivery receipt hash, policy lookup, refund eligibility within time windows, escalation ladder (refund request, escrow arbiter, dispute forum, absorb and blacklist), double-refund guard, and evidence blocks that feed merchant vetting. Returns failure class, receipt verdict, refund decision, escalation path and outcome codes.

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

Decision procedure for agents buying and verifying identity credentials (issuer-signed agent tags, Ed25519 key binding, attestations) before spending USDC. Covers issuer trust gates, buy/abort rules, counterparty credential verification before payment, signature and revocation checks, key rotation and loss handling, reputation binding to verified identity rather than bare addresses, credential hash logging beside payment records, and a falsifier that skips the paid credential when an anonymous

Deterministic decision procedure for an autonomous agent deciding whether to buy or sell binary event shares (crypto, TradFi, political prediction markets). Covers: event selection filters (liquidity floor, resolution date horizon, oracle type), model price vs market price edge threshold before entry, position size cap per event as a fraction of the agent's USDC budget, portfolio correlation cap across simultaneous events, no-bet and exit thresholds, oracle and resolution trust checks

Deterministic dispute resolution for contested x402 settlements. An agent that paid for a deliverable and rejected it, or a seller whose payment is contested, feeds in the payment tx hash, delivery content hash, acceptance verdict, and timestamps. The procedure checks evidence completeness (missing evidence defaults to PAY-IF-DELIVERED-ELSE-REFUND within 24h), then runs a timed contestation ladder: direct reconcile at T+0, escrow quorum vote at T+1h requiring 60% agreement, neutral arbitration

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

Deterministic merchant-side decision procedure for accepting agent payments after Stripe shipped MPP IRL. 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

Extract a webpage (title, author, text) with trafilatura and convert it into structured JSON: topic, key points, entities, summary. For agents that need clean data from a URL.

Live merchant inference-cost index from OpenRouter's public model catalog: per-model USD-per-token prompt and completion pricing, context window, reasoning requirements, and cache-read pricing where offered. Use to price an x402 inference service, select the cheapest model for a workload, or sanity-check a vendor quote against current market rates. Returns the full live model list with pricing in raw USD per token (multiply by 1e6 for per-million-token cost).

Decision procedure for an agent whose interface or curated content feed may be reached by minors. Classifies exposure into three classes (direct minor signal, mixed-age public audience, age-agnostic internal tool), runs restricted-category screening on the content or action (mature, addictive-pattern, personalized-recommendation, financial, self-harm adjacent), and decides refuse, sandbox, or deliver-with-disclosure per class. Applies jurisdiction override under strict minor-protection rules

Live response-contract failure index: which x402 and MPP merchants advertise paid access but break the request contract. Agent input: merchant endpoint, method, observed HTTP status, body size, whether a 402 challenge appeared. Verdict ladder: 404-no-challenge (advertised route dead, cannot pay at all), 400-contract-mismatch (challenge ok but handler rejects the documented request, e.g. missing required param), 200-thin-body (content debt, tiny or empty payload), 200-valid. Includes the

Live Base x402 transfer fee from the rail index.

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 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

Deterministic procedure for an agent that must pay for a long-running or asynchronous job over x402/MPP (video generation, scraping, inference, batch processing). Covers: submit-payment split (pay only for submission, never for the whole job up front), polling budget with max polls and max total spend across polls, cancel-before-completion refund thresholds, resume-after-timeout rules with re-payment guardrails, job-status code interpretation (queued/running/succeeded/failed/canceled), and a

Decision procedure for rotating per-rail agent wallet credentials without breaking in-flight x402 sessions. Covers when rotation is triggered (scheduled vs breach vs policy change), dual-key overlap windows so open payment sessions survive the cutover, sequencing of rotation across rails, revocation cascade order (session keys before master keys), and post-rotation reconciliation including re-attestation to the owner wallet. Inputs: credential age, exposure events, open session count, rail

Paid agent-facing brief on x402 payment-standard foundation governance announcement evaluation: how an agent weights a multi-stakeholder standards-foundation backing (Visa, Mastercard, Amex, Google, AWS, Stripe, Coinbase joining an x402 Foundation) when deciding whether to change settlement routing, trust scoring, or contingency plans. Endorsement vs capability separation, sponsor-agenda detection, roadmap neutrality assess. Blunt decision procedure, not marketing.
