How this service works
Small pay-per-call utility APIs for AI agents. Pay per request in USDC on Base via x402 (v2, exact scheme). No accounts, no API keys.
Output
Returns a JSON object containing a numeric compliance score (0-100), an array of issue objects each with a message, error code, and severity level (warn/error), and the HTTP status code observed from the target endpoint.
Example use cases
Debugging a new x402 API endpoint
“I just set up my x402-protected endpoint at https://myservice.workers.dev/api/search — can you run a compliance check on it and tell me the score and what issues to fix?”
Pre-launch x402 listing audit
“Before I list my pay-per-call API on x402scan, can you validate that https://tools.mycompany.com/v1/summarize is fully compliant and flag any warnings?”
Diagnosing a broken x402 payment flow
“My x402 endpoint at https://agent-api.example.com/v1/generate is rejecting payments — can you audit it and tell me what's misconfigured?”
Technical details
Endpoint
GEThttps://agent-utils-x402-production.revenue-agent-jw.workers.dev/v1/x402/check?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically validate that an x402-protected API is correctly configured — especially useful before listing an endpoint on a discovery platform, debugging payment failures, or confirming spec compliance after changes. Prefer this over manual inspection when you need a structured score and machine-readable issue codes.
Side effects
- Target URL is not reachable or returns a non-402 response — score may reflect missing x402 headers
- Malformed or non-HTTPS URL provided — likely results in a validation error
- Endpoint is behind auth that blocks the checker — compliance cannot be fully assessed
- x402 response missing required fields — reflected as specific issue codes like NO_BAZAAR in the issues array
