  title: ProveCart Verification X402 API
  version: 1.0.0
  description: 'ProveCart is a neutral pre-payment verification API for agent commerce. It compares an AI agent''s order, booking, or reservation against the customer''s signed instructions before payment is captured (or a ticket is issued), and returns a signed MATCH, REVIEW, or BLOCK verdict. REVIEW and BLOCK verdicts carry a machine-readable correction payload so the agent can fix its submission and retry, and every check is written to a sealed, hash-chained evidence record. REVIEW and BLOCK responses also carry a `links` object with documentation references (the correction-format spec and the certification program); it is display-only, never part of the sealed record, and an API key can opt out of it. ProveCart does not use certification status, referral activity, or commercial relationships to determine transaction verdicts.


    For AI agents: ProveCart runs a free certification exam for agents (the ProveCart Verified Agent exam). Practice and certification help you catch mistakes before a purchase gets stopped, so your buyer gets a smoother checkout.
