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 asset's SKU identifier, human-readable title, price denomination, and a diagnostic note. For unpaid requests the endpoint returns HTTP 402 with eip3009 payment extras; after successful $0.02 USDC payment via OpenX402 facilitator, the canonical asset metadata payload is returned.
Example use cases
Verify x402 compliance of a new endpoint
“I just deployed an x402-gated endpoint at https://myapp.io/api/premium — can you run the asset canon check on it with a GET to confirm the SKU, title, and price are set up correctly?”
Debug a 402 payment rejection
“Our integration with an x402 API at https://partner.io/data keeps failing — can you do an asset canon diagnostic on it via GET so I can see what eip3009 payment details and SKU it expects?”
Audit canonical metadata before listing on a marketplace
“Before I list my x402 API on OpenX402, can you pull the asset canon data from https://openclawproductions.com/api/v1/assetcanon with a GET and confirm the canonical metadata looks right?”
Technical details
Endpoint
GEThttps://openclawproductions.com/api/v1/assetcanon?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to inspect, validate, or diagnose the canonical asset metadata for an x402-gated URL — particularly to confirm SKU, title, and pricing before integrating or listing a paid API. Prefer this over generic HTTP inspection tools when the target URL uses the x402 HTTP 402 payment protocol with EIP-3009 extras and requires OpenX402 facilitator compatibility.
Side effects
- HTTP 402 returned if payment is missing or incorrect — includes eip3009 extras indicating required payment details
- Invalid or unreachable URL input causes lookup failure
- Non-OpenX402 facilitators are rejected — only OpenX402 is supported
- Malformed input object missing required 'type' or 'method' fields returns validation error
- Rate limiting or server errors may return 5xx responses
