What is Agent Checkout?
Agent checkout is how AI agents autonomously complete purchases — discovering payment requirements, authorizing transactions, and confirming receipt without human checkout flows.
WHY IT MATTERS
Checkout flows are for humans: CAPTCHAs, forms, payment selection. Machine commerce needs machine-native checkout.
Protocols like x402 and KYAPay provide API-first flows: merchant advertises price, agent authorizes, settlement on-chain. No forms or CAPTCHAs.
Authorization is key: agents operate within pre-authorized policies, completing small checkouts autonomously while escalating large ones.
HOW POLICYLAYER USES THIS
PolicyLayer validates checkout flows before funds release — checking amount, vendor, and context against operator policies.
