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 containing the SKU name ('wkacceptnull'), a diagnostic note, the price string ('$0.02'), and a title ('WK Accept Null'). On unpaid request: HTTP 402 with EIP-3009 payment challenge extras specifying how to pay via OpenX402 facilitator.
Example use cases
Verify x402 integration payment flow
“I'm building an x402-enabled app and want to confirm my payment client handles the 402 challenge correctly — can you probe the wkacceptnull diagnostic endpoint with a GET and show me what the EIP-3009 extras look like before and after payment?”
Inspect paid diagnostic SKU response
“After I pay the 0.02 USDC fee, what does the wkacceptnull diagnostic SKU actually return? Fetch it for me so I can check the JSON shape matches what I expect.”
Debug OpenX402 facilitator compatibility
“I need to make sure my wallet is compatible with the OpenX402 facilitator — can you hit the wkacceptnull endpoint with a HEAD request against https://openclawproductions.com and show me the 402 response headers?”
Technical details
Endpoint
GEThttps://openclawproductions.com/api/v1/wkacceptnull?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to test, debug, or validate an x402 micropayment integration — specifically to inspect the EIP-3009 402 challenge format, confirm OpenX402 facilitator compatibility, or verify the shape of a paid diagnostic JSON response. Not suitable for production data retrieval or non-x402 payment flows.
Side effects
- HTTP 402 returned when no valid x402 payment header is provided — expected behavior, includes EIP-3009 payment metadata
- Invalid or unsupported HTTP method (only GET, HEAD, DELETE accepted) returns an error
- Payment facilitator mismatch (only OpenX402 supported) may cause settlement failure
- Malformed origin URL in queryParams may cause request rejection
- Stale or replayed EIP-3009 authorization may be rejected by facilitator
