Real-time Japanese railway delays, line disruptions, station status, and route planning (ODPT-sourced, Tokyo area). Pay-per-call HTTP API using the x402 payment protocol (USDC on Base / Polygon / Solana) — no API key or signup. NOTE: this origin serves plain HTTP+x402, not the A2A JSON-RPC protocol; use the machine-readable interfaces below.

Decision procedure for an agent that paid an x402 endpoint and received a settlement receipt it cannot verify on-chain. Covers: opacity tier scoring (verifiable tx hash with explorer logs vs private-ledger claim vs screenshot or missing hash), accept / request-corrective-proof / escalate / blacklist verdicts per tier, what counts as a corrective proof (explorer URL, event-log match, signed receipt from facilitator), audit-trail requirements before escalating, recourse thresholds by payment size

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

Deterministic procedure for an agent that receives an HTTP 402 challenge on a rail or protocol version its payment client does not support. Inputs: rail identifier and version from the payment challenge headers, client support matrix, facilitator availability (PayAI, MPP gateway), budget floor. 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.

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

Paid agent-facing brief on Decision procedure for an agent evaluating a website's self-declared agent operation interface (WebMCP-style capability manifest) before executing any instruction from it: validate declared operations against the observed HTTP surface, reject self-serving or malicious operation declarations, check declared payment requirements against actual 402 challenges, single go/no-go verdict with failure modes.-0. 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.

Decision procedure for agents that pay while driving a browser session. Covers: when to auto-pay a 402 challenge mid-automation versus aborting, spend caps per navigation step, session reuse to avoid double-charging, and verification that the paid result (page, file, or API payload) actually arrived before continuing. Also covers Cloudflare programmable wallet reservations: how to verify a readable agent wallet ID/credential before trusting a seller, and how to reject requests from unverified

Paid agent-facing brief on pay-per-crawl economics for agents hitting Cloudflare-edge x402 gated websites: crawl depth vs cost budgeting, page-level verification of what was paid for, cache TTL reuse, and stop-loss thresholds for high-volume agent crawling-0. Blunt decision procedure, not marketing.

Decision procedure for provisioning a Cloudflare-style virtual wallet for an AI agent. Answers the questions every wallet issuer faces before the agent's first payment: which ERC-7715 permission scopes to grant, how a merchant gets onto the allowlist and what gets it removed, how to size the asset cap per spend category, what expiry windows make sense per permission, and how revocation is wired so a compromised or overreaching agent loses spend capability before it drains the wallet. Includes

Machine-executable decision procedure for agents that must translate text and decide which translation rail to pay for. Returns a verdict per translation job: premium machine translation (DeepL-class) vs frontier LLM translation vs free API vs deferred. Includes language-pair routing, quality gates with back-translation spot checks, glossary and domain handling, per-document cost caps, and fallback order. Inputs: source text, target language, domain, glossary terms, decision value, budget cap,

Agent-facing decision procedure for choosing which onchain data layer to pay for a given query. Covers query class routing: raw RPC for state and balances, indexed explorer APIs for receipts and status, analytics warehouses for flows, whales, and decoded events. Covers cross-chain coverage decisions, per-provider cost guardrails, rate-limit handling, confirmation-depth and finality checks before acting on onchain truth, and an evidence log schema linking each decision to the source payload.

Paid agent-facing brief on Agent identity rank fallback thresholds: decision procedure for ranking multiple agent identity signals (ERC-8004 claims, credentials, wallet signatures, facilitator endorsements) and applying fallback thresholds when the primary verification path is unavailable or partially verifiable. Outputs ACCEPT, ACCEPT_WITH_CAVEATS, REQUIRE_ISSUER_CONFIRMATION, REJECT with per-source authority ranking and threshold math.. Blunt decision procedure, not marketing.

Paid agent-facing brief on x402 challenge payability and payment-scheme compatibility check: agent-side procedure that grades an incoming 402 challenge before any signature is attempted, verifying challenge version (v1 vs v2), network scheme (eip155: 8453, solana, xrpl, skale), whether the agent's wallet client has a registered scheme for that network, and price against spend caps. Returns single verdict: payable now, payable after upgrade, or unpayable with reason.. Blunt decision 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
