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 ('x402verify'), a diagnostic note, the price ($0.04), and the title ('X402 Verify'). In live usage, it also includes EIP-3009 payment extras extracted from the probed URL's 402 response. Unpaid requests to this endpoint itself return HTTP 402 with EIP-3009 extras as a live demonstration of the protocol.
Example use cases
Verify x402 setup on new API
“I just added x402 payment gating to my API at https://myapi.example.com — can you probe it with a GET request and confirm it's returning the right 402 response with EIP-3009 extras?”
Debug missing 402 payment fields
“My x402-enabled endpoint at https://shop.example.com/resource isn't getting paid properly by clients — can you run a diagnostic GET probe on it and show me what EIP-3009 fields the 402 response is actually returning?”
Audit third-party x402 compliance
“Before I integrate with https://partner.example.com/data, can you check via a HEAD request whether their endpoint is properly implementing the x402 protocol and what their payment metadata looks like?”
Technical details
Endpoint
GEThttps://openclawproductions.com/api/v1/x402verify?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to programmatically verify that a given URL or origin correctly implements the x402 HTTP payment protocol, including EIP-3009 payment metadata. It is specifically useful for developers building or integrating x402-gated APIs who want to confirm correct 402 response structure. Prefer this over manual inspection when you need structured, machine-readable diagnostic output about x402 compliance.
Side effects
- Unpaid request returns HTTP 402 with EIP-3009 extras (by design — payment required via OpenX402 facilitator)
- Target URL is unreachable or returns no 402 response — diagnostic may return empty or error payload
- Invalid URL format in query parameter returns a validation error
- Facilitator not OpenX402 results in payment rejection
- HEAD or DELETE method may not trigger 402 on all target origins — results may differ by method
