How this service works
Paid x402 diagnostics. Unpaid paid-SKU requests return HTTP 402 with eip3009 extras. Facilitator: OpenX402 only.
Output
A JSON object containing the SKU identifier ('settlecoupon'), a human-readable title ('Settle Coupon'), the price ('$0.20'), and a diagnostic note confirming it is a paid response. If payment is not included, returns HTTP 402 with EIP-3009 payment-required metadata.
Example use cases
Verify x402 payment integration
“Can you hit the settlecoupon diagnostic endpoint for me? I need to make sure my x402 payment flow is set up correctly and that the OpenX402 facilitator is accepting my EIP-3009 authorization.”
Inspect 402 error response extras
“I want to see what the HTTP 402 response looks like when I don't include a payment — can you call the settlecoupon SKU without auth so I can inspect the eip3009 extras it returns?”
Confirm paid diagnostic payload shape
“Fetch the live settlecoupon paid JSON for me so I can verify the response shape — SKU, title, price, and note — matches what I'm expecting in my x402 integration.”
Technical details
Endpoint
GEThttps://openclawproductions.com/api/v1/settlecoupon?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to test or validate an x402 micropayment integration using a real live paid API, specifically one gated by EIP-3009 authorization and settled through the OpenX402 facilitator. It is ideal for developers debugging 402 payment flows, verifying USDC micropayment headers, or confirming that a paid response payload is correctly structured.
Side effects
- HTTP 402 returned if no valid x402/EIP-3009 payment header is provided, along with eip3009 extras describing payment requirements
- Non-OpenX402 facilitators rejected — only OpenX402 is accepted as facilitator
- Invalid or expired EIP-3009 authorization causes payment rejection
- Malformed input properties may result in unexpected behavior due to loose input schema
