x402 Trust Layer Receipt Auditor

Use this endpoint when you need to audit or verify whether a specific x402 paid HTTP request (GET, HEAD, or DELETE) was properly settled and authorized. Prefer this over mandate-status or escrow endpoints when you already have a receipt and need a simple allowed/not-allowed audit result with a human-readable summary.

• Missing required 'type' or 'method' fields returns a 400 validation error
• Unsupported HTTP method (e.g. POST or PUT) for the input schema causes a schema validation failure
• Invalid or expired payment receipt may return allowed: false with an explanatory summary
• x402 settlement not found on-chain may result in ok: false response
• Network or upstream facilitator timeout returns a 5xx error
