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 SKU identifier ('wwwauthmiss'), a human-readable title ('WWW Auth Miss'), the price ($0.02), and a diagnostic note describing the 402 payment gate behavior of the probed endpoint. Unpaid requests return HTTP 402 with eip3009 extras describing the required payment.
Example use cases
Verify 402 gate on new API
“I just deployed a paid API endpoint at https://myapp.com/premium-data — can you run an x402 diagnostic with a GET request to check whether the 402 response and payment metadata are set up correctly?”
Debug payment wall misconfiguration
“My x402-gated endpoint at https://myservice.io/api/report seems to be rejecting payments even after settlement — can you probe it with a GET and show me what eip3009 extras it's returning?”
Audit third-party 402 endpoint
“Before I integrate with https://partner.com/api/data, can you run an x402 diagnostic on it using a GET request so I can see its SKU, price, and whether it's properly returning 402 with eip3009 metadata?”
Technical details
Endpoint
GEThttps://openclawproductions.com/api/v1/wwwauthmiss?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to verify that a specific public URL correctly implements the x402 payment protocol, including proper HTTP 402 status codes and eip3009 payment metadata. Prefer this over generic HTTP probing tools when the goal is specifically to audit or debug x402 payment gates, confirm OpenX402 facilitator compatibility, or validate eip3009 extras on a paid-SKU endpoint.
Side effects
- Unpaid request returns HTTP 402 with eip3009 payment requirement — agent must settle payment before accessing result
- Invalid or unreachable URL returns an error or empty diagnostic
- Non-public or firewall-protected origin URLs cannot be probed
- Facilitator other than OpenX402 is rejected — only OpenX402 is supported
- Malformed input (wrong HTTP method outside GET/HEAD/DELETE) returns validation error
