The core OpenPermit objects and flows behind machine payment authorization.
OpenPermit sits between agent workflows and payment execution. It normalizes payment challenges into payment intents, evaluates them against mandates, executes or prepares credentials, and records receipts and audit evidence.
Mandates
Approved, revocable spending authority for an agent.
Authorization evidence
Portable proof that an agent was authorized to act, including VI/AP2, Web Bot Auth, and provider credentials.
HTTP payments
How x402, MPP, and onchain challenges become OpenPermit payment intents.
Receipts and audit
How payment execution, delivery, and policy decisions are recorded.
Auth and orgs
How organizations, service accounts, roles, and capabilities gate API access.
