Discover pay-per-request API endpoints for a given capability.
Returns ranked, verified endpoints with pricing and reliability metrics.
Use this to find APIs before calling them. The results include:
- Endpoint URL and method
- Price per call and payment network
- Success rate and latency metrics
- Provider information
- sample_request / sample_response: Example request body and response showing the exact parameter names and format the endpoint expects. ALWAYS use sample_request as your template when calling the endpoint — do not guess parameter names.
After discovering, you can use call_paid_api to execute the endpoint.
Trust & safety:
- "Verified" means the endpoint returns a valid x402 402 response -- it does not guarantee the quality or accuracy of the data returned after payment.
- Endpoints are probed every 10 minutes. Check last_verified and success_rate to gauge reliability.
- Fallback endpoints (unverified) have failed recent verification checks -- use with caution.
- Prefer endpoints with success_rate >95% and verification within the last 24 hours.
