Output
Returns an audit/validation report indicating whether the payment receipt is valid, whether the transaction hash is confirmed settled, and whether the payment payload matches the payment requirements. May flag discrepancies between the receipt and requirements.
Example use cases
Confirm micropayment before releasing content
“I just received a payment receipt from an x402 client — the transaction hash is 0xdeadbeef... on Base mainnet. Can you audit the receipt and confirm the payment actually settled before I unlock the gated API response?”
Troubleshoot a rejected x402 payment
“My agent tried to pay for an x402-gated endpoint and got back a receipt, but the server rejected it. Here's the receipt object and the original payment payload — can you audit them together and tell me what's wrong?”
Validate facilitator payment payload pair
“I have an x402 payment payload and the matching payment requirements object from the facilitator. Can you run a receipt audit to verify they match up correctly and the payment is legitimate?”

Choose this endpoint when you need to programmatically audit or verify an x402 payment receipt before granting access to a paid resource, troubleshoot a payment dispute, or confirm that a settle transaction hash is valid and matches the stated payment requirements. Best for x402 protocol flows on Base or compatible networks.
Side effects
- Missing required receipt or transaction hash returns validation error

- Network mismatch between receipt and requirements causes rejection
- Malformed payment_payload or payment_requirements object causes parse failure
- Payment not yet settled on-chain returns pending or unconfirmed status
