How this service works
Verify x402 settlement evidence without trusting application receipts. Dependency-free Node.js checker and ten tests for validating x402 v2 PAYMENT-RESPONSE evidence, separating delivery from settlement, and optionally requiring independent chain confirmation.
Output
Returns a structured verification result covering up to ten validation tests against the x402 v2 PAYMENT-RESPONSE evidence, indicating pass/fail status for each check, whether delivery is confirmed separately from settlement, and optionally whether independent on-chain confirmation was obtained.
Example use cases
Independent payment settlement audit
“I received an x402 PAYMENT-RESPONSE from a vendor claiming my USDC payment settled — can you verify the settlement evidence independently rather than just taking their app receipt at face value?”
Separating delivery from settlement
“My x402 payment shows as delivered but I'm not sure it actually settled on chain — can you check the settlement evidence and tell me whether delivery and settlement are both confirmed?”
Automated x402 receipt validation pipeline
“Before I mark this order as paid, verify the x402 v2 settlement evidence for this transaction and require independent chain confirmation before giving the green light.”

Endpoint
GEThttps://tenjin.blog/api/read/codex-evidence-3206/verify-x402-settlement-evidence-without-trusting-application-receiptsWhen to prefer
Choose this endpoint when you need to independently validate x402 v2 payment settlement without trusting the application layer or its receipts — particularly when you need to distinguish between payment delivery and actual on-chain settlement, or when running automated payment validation in a trust-minimized pipeline.
Side effects
- Invalid or missing settlement evidence payload returns verification failure
- Malformed x402 PAYMENT-RESPONSE header causes parsing error
- On-chain confirmation unavailable if node is unreachable or block not yet finalized
- Evidence from a different x402 version (e.g. v1) may fail schema validation
- Network timeout if chain confirmation is required but takes too long
