How this service works
X402 micropayments server — AI agents pay USDC for OFAC screening, rates, and billing verification.
Output
A JSON object containing a 'success' boolean and a 'result' object with settlement details for the given transaction hash, including payment status and any associated receipt metadata.
Example use cases
Confirm agent payment completed
“I just had an AI agent pay for an OFAC screening via x402 — can you verify the settlement receipt for transaction hash 0x3f8a2c1d...b9e4 and confirm the payment went through?”
Audit micropayment billing record
“Pull up the receipt for x402 transaction 0xd4c7b2e1...a3f9 so I can confirm the USDC billing charge is accurate before I approve this month's agent spending report.”
Debug failed API call payment
“My agent tried to pay for an API call using x402 but I'm not sure if the USDC settled — check transaction hash 0x12fe87a3...c6d2 and tell me what the receipt says.”
Technical details
Endpoint
GEThttps://x402helper.xyz/529639/api/settle/receipt?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to verify or retrieve a receipt for a specific x402 micropayment settlement identified by its transaction hash. It is purpose-built for confirming USDC micropayment completions in x402 agent-to-agent payment flows, particularly useful for auditing, debugging, or confirming billing after a pay-per-call API interaction.
Side effects
- Missing or malformed 'tx' query parameter returns 400 before payment is charged
- Invalid transaction hash format (not 0x + 64 hex characters) returns 400
- Transaction hash not found on-chain or not a valid x402 settle transaction returns an error result
- Payment of 0.013 USDC required before response is served; unpaid requests receive 402
