How this service works
Paid x402 diagnostics. Unpaid paid-SKU requests return HTTP 402 with eip3009 extras. Facilitator: OpenX402 only.
Output
Returns a JSON object containing the diagnostic SKU identifier ('ct402'), a title, price, and a note describing the x402 payment flow result. Indicates whether the target URL correctly returns HTTP 402 with valid EIP-3009 payment extras when unpaid, and confirms OpenX402 facilitator compatibility.
Example use cases
Verify x402 compliance before launch
“Before I publish my new paid API, can you run an x402 diagnostic on https://myservice.com/api/premium to confirm it returns HTTP 402 with the right EIP-3009 payment metadata?”
Debug broken 402 payment gate
“My x402-gated endpoint at https://dev.example.com/data seems to be misbehaving — can you probe it with a GET request and tell me what the 402 diagnostic shows about the payment flow?”
Spot-check x402 setup on a known URL
“Can you use the x402 pipe check to inspect https://openclawproductions.com and see if the x402 payment flow and EIP-3009 extras are configured correctly?”
Technical details
Endpoint
GEThttps://openclawproductions.com/api/v1/ct402?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to verify, debug, or validate that a specific public URL correctly implements the x402 HTTP payment protocol, especially EIP-3009 payment extras. It is purpose-built for x402 compliance checking and works specifically with the OpenX402 facilitator. Prefer it over generic HTTP inspection tools when the focus is x402/EIP-3009 payment flow correctness.
Side effects
- Unpaid request returns HTTP 402 with eip3009 extras instead of diagnostic result — must include valid payment
- Target URL is unreachable or not a valid public URL — returns error or empty diagnostic
- URL does not implement x402 protocol — diagnostic may return unexpected or incomplete results
- Invalid HTTP method provided — only GET, HEAD, DELETE are accepted
- OpenX402 facilitator unavailable — request cannot be processed
