AI agent API payments
AI agents increasingly pay for API access - inference providers, data feeds, search APIs, enrichment services. Agent Commerce adds a verifiable record to every API spend: what was authorized, what executed, and how to verify it.
What Agent Commerce adds to API payments
Policy before execution
Before any API call is paid for, the authorization engine checks rail, currency, merchant, amount, and purpose tag against the agent's policy.
Signed receipt per call
Every successful API payment produces a payment_receipt.v1 artifact - signed with Ed25519, hashed with SHA-256, independently verifiable.
Purpose tag audit trail
Each receipt carries a purpose_tag (e.g. api_call) that links the spend to its intended category - enabling downstream governance reporting.
Independent verification
Any party can verify an API payment receipt using the public GET /api/payments/verify/:receiptId endpoint. No account required.
Launch API payments with proof built in
Start in sandbox, then move into production with signed receipts, policy enforcement, and verification surfaces that external systems can trust.
