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 SKU name ('schememix'), title, price, and a note field — along with any x402/EIP-3009 payment extras embedded in the 402 response. On unpaid requests the endpoint itself returns HTTP 402 with payment challenge details.
Example use cases
Verify 402 compliance before integrating
“I'm about to integrate with an external API that claims to support x402 payments — can you run the schememix pipe check on https://partner.io/api/data with a GET request to confirm it returns proper 402 payment metadata?”
Debug broken x402 payment flow
“My x402 payment flow isn't working for https://myapp.com/premium-endpoint — can you probe it with a GET request using schememix diagnostics and tell me what EIP-3009 extras and payment info it's returning?”
Audit new x402-gated origin
“I just deployed a new paid API at https://newservice.example.com and want to make sure the x402 scheme is configured correctly — can you run schememix diagnostics on that origin with a HEAD request to see what the 402 response looks like?”
Technical details
Endpoint
GEThttps://openclawproductions.com/api/v1/schememix?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to diagnose, validate, or inspect x402 HTTP 402 payment flows for a specific URL or origin — particularly to verify EIP-3009 payment metadata, check scheme compliance, or debug payment gating. It is specialized for x402 protocol diagnostics via OpenX402 facilitator only, not for general HTTP inspection or non-x402 payment systems.
Side effects
- HTTP 402 returned if the $0.03 USDC payment is not included — includes EIP-3009 payment challenge extras
- Invalid or unreachable target URL results in probe failure
- Non-GET/HEAD/DELETE HTTP methods rejected by schema validation
- Missing required 'type' or 'method' fields returns validation error
- Facilitator other than OpenX402 not supported
