Field notes
The documented payment flow starts with an unpaid POST /verify request, which returns HTTP 402 requirements for a compatible x402 client to handle before retrying. The sample output includes evidence, sources, confidence, an explanation, and a timestamp. The security section cautions that this signal does not replace wallet policy, approvals, transaction simulation, or deterministic controls.
