How this service works
Paid x402 diagnostics. Unpaid paid-SKU requests return HTTP 402 with eip3009 extras. Facilitator: OpenX402 only.
Output
Returns a JSON object containing the SKU name ('claimproof'), a human-readable title ('Claim Proof'), the price ('$0.03'), and a diagnostic note confirming the paid JSON shape. This serves as proof that the x402 payment was accepted and the EIP-3009 authorization was valid.
Example use cases
Verify x402 payment integration end-to-end
“I just wired up the x402 payment flow in my app — can you call the claimproof endpoint to confirm the $0.03 USDC payment settles correctly and returns a valid proof JSON?”
Debug HTTP 402 error in x402 setup
“My app keeps getting a 402 back from the claimproof SKU even after I send payment — can you try calling it with a proper EIP-3009 auth and show me what the settled response looks like?”
Audit OpenX402 facilitator claim output
“I need to check what a successful OpenX402 facilitator settlement actually returns for the claimproof SKU — can you fetch it and show me the full diagnostic payload?”
Technical details
Endpoint
GEThttps://openclawproductions.com/api/v1/claimproof?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to verify that an x402 micropayment flow — specifically using EIP-3009 and the OpenX402 facilitator — is working correctly end to end. It is the right choice for testing, debugging, or auditing x402 payment integrations at the claimproof SKU level, not for general content retrieval or non-crypto payment validation.
Side effects
- HTTP 402 returned with EIP-3009 extras if payment is missing or invalid — indicates unpaid or malformed micropayment
- Invalid or expired EIP-3009 authorization token causes payment rejection
- Wrong facilitator (non-OpenX402) may result in payment not being recognized
- Malformed request properties field may yield unexpected or empty response
- Network timeout or service unavailability returns no diagnostic payload
