How this service works
Paid x402 diagnostics. Unpaid paid-SKU requests return HTTP 402 with eip3009 extras. Facilitator: OpenX402 only.
Output
A JSON object containing the SKU name ('sampfree200'), a human-readable title ('Samp Free 200'), the price ('$0.02'), and a diagnostic note. Unpaid requests receive an HTTP 402 response with EIP-3009 payment extras instead.
Example use cases
Verify x402 pipe check on live URL
“Can you probe my API at https://myapp.example.com to check whether it's correctly returning HTTP 402 with eip3009 extras when payment is missing? Use a GET request and pay the $0.02 diagnostic fee.”
Debug failing x402 payment integration
“My x402-gated endpoint keeps rejecting payments — can you run a paid diagnostic GET check against it to see what the 402 response looks like and whether the eip3009 fields are set up right?”
Confirm OpenX402 facilitator compatibility
“I need to make sure my API is compatible with the OpenX402 facilitator — can you do an x402 diagnostic probe on https://myservice.io/api/resource using GET and show me the SKU and payment details in the response?”
Technical details
Endpoint
GEThttps://openclawproductions.com/api/v1/sampfree200?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to test, validate, or debug an x402 micropayment-gated API endpoint, specifically to verify that HTTP 402 responses and EIP-3009 payment extras are correctly implemented. Prefer this over generic HTTP probes when you need x402-protocol-aware diagnostics and are using the OpenX402 facilitator.
Side effects
- HTTP 402 returned with eip3009 extras if payment header is missing or invalid
- Invalid URL input causes probe to fail or return error
- Non-GET/HEAD/DELETE method rejected by input schema
- Facilitator not OpenX402 will result in payment rejection
- Malformed origin/url query parameter returns error
