How this service works
Score one x402 resource for trust, schema, price, discovery, and receipt readiness.
Output
Returns a JSON object with an 'ok' boolean, the tool name ('trust.score_resource'), and a 'recommendation' string (e.g. 'test-first') indicating whether and how cautiously to proceed with purchasing the x402 resource.
Example use cases
Example prompt
“Before I pay for this x402 resource at https://api.example.com/data (origin: https://api.example.com, priced at $0.05), can you score its trustworthiness — it has a 402 header, an OpenAPI spec, and a well-known file, but no receipt confirmation yet — and tell me if I should go ahead and buy?”
Technical details
Endpoint
POSThttps://trust402.aztecbeacon.uk/api/trust/score-resourceWhen to prefer
Use this endpoint when an AI agent or buyer is about to execute a payment against an x402-gated resource and needs a pre-purchase trust signal. Prefer it over general URL reputation services when the target resource uses the x402 HTTP payment protocol and you need procurement-specific signals like receipt readiness, OpenAPI presence, and well-known file availability.
Side effects
- Missing or invalid endpoint/origin URL returns a 400-level error
- Resource signals are ambiguous leading to a conservative 'test-first' or 'avoid' recommendation
- Endpoint unreachable or timeout if the origin cannot be probed
- Invalid priceUsd or schema types cause request rejection
