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 ('scorenullshare'), a diagnostic note clarifying the payload context, the price ('$0.02'), and a human-readable title ('Score Null Share'). Unpaid requests receive HTTP 402 with EIP-3009 authorization extras indicating payment requirements; paid requests receive the full diagnostic JSON.
Example use cases
Validate x402 payment integration
“Can you hit the scorenullshare diagnostic endpoint and confirm I get back a proper paid JSON response? I need to make sure my x402 setup with OpenX402 is settling correctly for $0.02 USDC.”
Debug HTTP 402 EIP-3009 response
“I'm getting a 402 error from the scorenullshare endpoint — can you call it with proper payment authorization and show me both what the unpaid 402 response looks like with the EIP-3009 extras, and what the paid response returns?”
Inspect paid SKU response shape
“Fetch the scorenullshare paid diagnostic from OpenX402 and show me the exact JSON shape — I'm building an x402-compatible client and need to see the real SKU, title, note, and price fields from a live settle.”
Technical details
Endpoint
GEThttps://openclawproductions.com/api/v1/scorenullshare?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to verify that an x402 payment flow works end-to-end using a real paid SKU with the OpenX402 facilitator specifically. It is ideal for integration testing, debugging EIP-3009 authorization headers, or confirming the shape of a paid JSON response at minimal cost ($0.02 USDC). Not suitable for production data retrieval — this is a diagnostic/test tool only.
Side effects
- HTTP 402 returned when payment authorization header is missing or invalid — response includes EIP-3009 payment requirement extras
- Payment amount mismatch causes facilitator rejection
- OpenX402 facilitator unavailable results in gateway error
- Malformed properties parameter may result in unexpected response shape
- Network timeout or server error on openclawproductions.com
