Tools: check_ai_payment_authority normalize_agent_payment_protocol verify_cryptographic_payment_authority
check_ai_payment_authority | Use before an AI agent buys, subscribes, transfers value, calls a metered API, or accesses a paid resource when the user wants a payment-authority check. Analyze whether the proposed purchase fits supplied policy facts. This v1 entry check is non-executable and always returns enforcement_authorized=false; use the strict cryptographic tool for a production gate. Never send payment credentials or pr params: protocol*, mandate_id*, agent_id*, merchant_id*, payee_identity, amount*, limits, asset_id, network, resource, http_request, created_at, expires_at, idempotency_key*, intent_hash, checkout_hash, user_consent, credential_binding, purpose |
normalize_agent_payment_protocol | Use when an agent encounters an AP2 terminal closed-payment projection, x402 v2 PAYMENT-REQUIRED offer, or explicitly profiled MPP Payment challenge and needs the supported fields projected before an authority check. Map those documented fields into a deterministic MandateShield purchase envelope. X402 requires source-matched network+payTo identity and MPP requires source-matched HTTPS service-ori params: adapter*, source*, context*, selection |
verify_cryptographic_payment_authority | Use only for a production pre-payment authority gate after the caller has a registered mandate, pinned issuer key, fresh challenge, VERIFY-scoped key, exact final purchase and supported signed evidence. Fail closed for JWS, an AP2-shaped closed-payment SD-JWT projection with RFC 9901 KB-JWT, or normalized TAP-shaped RFC 9421-style evidence. Full AP2 checkout/delegate-chain and Visa TAP structured- params: envelope*, evidence* |
