How this service works
Check whether a seller endpoint is ready for marketplace discovery and autonomous buyers.
Output
A JSON object with an 'ok' boolean indicating success, a 'tool' field identifying the check performed ('seller.readiness'), and a 'recommendation' string (e.g. 'test-first') advising the buyer agent on how to proceed with the resource.
Example use cases
Example prompt
“Before my agent pays to call this x402 resource at https://api.example.com/data, can you run a seller readiness check on it — it costs $0.05, has a 402 response, has an OpenAPI spec, has a well-known file, and its receipt endpoint is ready?”
Technical details
Endpoint
POSThttps://trust402.aztecbeacon.uk/api/seller/readinessWhen to prefer
Use this endpoint when an AI agent or automated buyer is about to pay for an x402-gated resource and needs a pre-flight trust assessment before committing funds. Prefer this over manual inspection when you have structured metadata about the seller endpoint (has402, hasOpenApi, hasWellKnown, receiptReady, hasInputSchema) and want a machine-readable recommendation on procurement risk.
Side effects
- Missing or malformed origin/endpoint URI returns validation error
- Invalid price format causes schema rejection
- Endpoint unreachable or returns unexpected non-JSON response
- Incomplete input flags may result in low-confidence or ambiguous recommendation
- Network timeout if upstream trust evaluation service is slow
