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 with fields including the SKU name ('corspayexpose'), a human-readable title ('CORS Pay Expose'), the price ($0.02), and a diagnostic note. On unpaid requests, returns HTTP 402 with EIP-3009 payment extras indicating the required payment details for settlement via OpenX402.
Example use cases
Verify x402 endpoint payment configuration
“Can you probe https://myapi.example.com with a GET request using the x402 CORS pay-expose check and tell me if it's returning the right EIP-3009 payment extras?”
Debug 402 response on HEAD request
“I need to diagnose why my x402-gated API at https://api.myservice.io isn't settling — can you run the CORS pay-expose diagnostic on it using a HEAD method and show me what comes back?”
Confirm OpenX402 facilitator CORS setup
“Check if https://openclawproductions.com is properly configured as an x402 origin by running a GET-based CORS pay-expose diagnostic and showing me the SKU, price, and any CORS payment headers.”
Technical details
Endpoint
GEThttps://openclawproductions.com/api/v1/corspayexpose?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to programmatically verify that an x402-gated URL is correctly configured for CORS-based micropayments, particularly when using the OpenX402 facilitator and EIP-3009 payment authorization. It is the right tool for diagnosing 402 payment flows, inspecting CORS headers on payment-gated APIs, or confirming that an origin is properly exposing x402 payment metadata — not for general HTTP inspection or non-payment CORS debugging.
Side effects
- HTTP 402 returned if payment header is missing or invalid — includes EIP-3009 extras for payment resolution
- Invalid or unreachable target URL returns an error or empty diagnostic
- Non-GET/HEAD/DELETE methods rejected due to enum constraint
- Missing required 'type' or 'method' fields in input causes validation failure
- OpenX402 facilitator unavailability may block payment settlement
