How this service works
Verify an x402 payment settled: tx hash -> status, amount, from/to, block
Output
Returns the on-chain settlement status of the transaction (e.g. confirmed, pending, failed), the payment amount, the sender and recipient wallet addresses, and the block number in which the transaction was included.
Example use cases
Confirm agent payment before delivering content
“Before I release the API response, check that the payment with tx hash 0xdef456... on the base network has actually settled — I need to see the status, amount, and the from/to addresses.”
Debugging a failed x402 transaction
“My x402 payment doesn't seem to have gone through — can you look up tx hash 0x789abc... on ethereum and tell me its current status and what block it landed in, if any?”
Audit trail for micropayment reconciliation
“I need a receipt for the transaction 0x111222... on base — pull up the settlement status, the amount paid, sender and recipient addresses, and the block number so I can log it.”
Technical details
Endpoint
POSThttps://predator-ubuntu.taild9a745.ts.net/v1/receipt?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to verify that a specific x402 micropayment has settled on-chain given a known transaction hash and network. It is purpose-built for the x402 payment protocol ecosystem and returns structured receipt data (status, amount, from/to, block) rather than raw blockchain data. Prefer this over generic blockchain explorers when operating within an x402-enabled agent workflow where you need a clean, structured confirmation before proceeding.
Side effects
- Transaction hash not found on specified network — returns not found or null status
- Invalid or malformed tx hash — returns validation error
- Network identifier unrecognized — returns bad request error
- Transaction still pending — status returned as pending with no block data
- RPC node unavailable for the specified network — returns upstream error
