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 name ('facpick'), a human-readable title ('Fac Pick'), the price ('$0.04'), and a diagnostic note confirming the paid response shape. Returns HTTP 402 with EIP-3009 payment details if the request is unpaid.
Example use cases
Testing x402 client payment integration
“I just wired up my x402 client library and want to make sure EIP-3009 payments actually go through — can you call the facpick endpoint, pay the $0.04 USDC, and show me the full JSON response so I know it's working end-to-end?”
Validating OpenX402 facilitator is live
“Check whether the OpenX402 facilitator is operational right now by hitting the facpick diagnostic endpoint and confirming it returns a successful paid response instead of a 402 error.”
Debugging HTTP 402 payment-required behavior
“My app keeps getting 402 errors from x402 endpoints — can you deliberately call the facpick SKU without paying first so I can see exactly what EIP-3009 extras come back in the 402 response?”
Technical details
Endpoint
GEThttps://openclawproductions.com/api/v1/facpick?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to test or validate x402 micropayment flows using a real paid API call via OpenX402 as the facilitator. It is purpose-built for diagnostics — not for production data retrieval. Prefer it over other x402 test endpoints when you specifically need to verify EIP-3009 authorization handling or OpenX402 facilitator selection behavior.
Side effects
- HTTP 402 returned when no valid EIP-3009 payment authorization is included — response body contains payment challenge with extras
- Invalid or expired EIP-3009 token causes payment rejection
- OpenX402 facilitator unavailable causes request failure
- Malformed properties parameter may result in unexpected response
- Network timeout if OpenX402 facilitator settlement is slow
