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 ('amounttype'), a human-readable title ('Amount Type'), the price ('$0.02'), and an example paid JSON shape. This is a diagnostic example response illustrating the structure of a paid x402 SKU, not a live settlement.
Example use cases
Inspect x402 endpoint payment metadata
“I want to check the amount type and paid SKU details for my x402-protected API at https://myapi.example.com — can you run the amounttype diagnostic against it?”
Verify 402 payment shape before integration
“Before I integrate with this x402 endpoint, can you probe https://partner.example.com/api/data using the amounttype diagnostic so I can see the EIP-3009 payment extras and price?”
Debug unexpected 402 response from x402 API
“I'm getting an unexpected 402 from https://openclawproductions.com/api/v1/amounttype — can you run the x402 amount type diagnostic on that origin to show me what payment shape it's expecting?”
Technical details
Endpoint
GEThttps://openclawproductions.com/api/v1/amounttype?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to inspect or validate the x402 payment amount type metadata for a specific URL or origin, particularly when debugging or integrating with x402-protected APIs that use the OpenX402 facilitator and EIP-3009 payment extras. It is a diagnostic tool best suited for developers and agents building x402 payment flows, not for production data retrieval.
Side effects
- HTTP 402 returned if the request is unpaid — includes EIP-3009 extras indicating required payment details
- Invalid or unreachable URL results in an error response
- Only GET, HEAD, and DELETE HTTP methods are accepted; other methods will be rejected
- The facilitator must be OpenX402; other facilitators are not supported and may cause errors
- Malformed input object (missing required 'type' or 'method' fields) causes a validation error
