How this service works
Paid x402 diagnostics. Unpaid paid-SKU requests return HTTP 402 with eip3009 extras. Facilitator: OpenX402 only.
Output
On successful payment: a JSON object with fields sku ('stubhold41'), note (example paid shape description), price ('$0.02'), and title ('Stub Hold 41'). On missing or invalid payment: HTTP 402 with EIP-3009 payment challenge extras specifying how to authorize the micropayment.
Example use cases
Verify x402 payment gating works
“Hit the stubhold41 diagnostic endpoint without paying first and show me the 402 payment challenge it returns — I need to confirm the eip3009 extras are formatted correctly.”
Confirm successful paid x402 response
“Authorize the $0.02 USDC payment via EIP-3009 and fetch the stubhold41 paid diagnostic so I can see what a successful x402 settled response looks like from OpenX402.”
Debug x402 facilitator integration
“I'm integrating with the OpenX402 facilitator and need to test it end-to-end — can you call the stubhold41 paid SKU endpoint and tell me whether the payment went through and what JSON came back?”
Technical details
Endpoint
GEThttps://openclawproductions.com/api/v1/stubhold41?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to test or validate an x402 micropayment integration end-to-end against a live paid SKU, specifically with the OpenX402 facilitator and EIP-3009 authorization. It is a diagnostic stub, not a production data service, so prefer it for protocol verification and developer debugging rather than real data retrieval.
Side effects
- HTTP 402 returned when no valid x402 payment header is provided — expected behavior, includes eip3009 payment challenge extras
- Invalid EIP-3009 authorization causes facilitator rejection before response is served
- OpenX402 facilitator unavailable results in gateway error
- Malformed properties parameter may be ignored silently as schema is loosely typed
