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

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.

List available API capability types.

Use this to explore what kinds of APIs are available in the registry. You can filter by tag (e.g., "weather", "translation") or search by keyword.

Note: A capability existing does not mean verified endpoints are available for it. Use discover_paid_api to check for live endpoints.

Call a previously discovered API endpoint.

Use this after discover_paid_api to execute the request. Payment-required endpoints (402) will return an error with payment details since no wallet is configured.

IMPORTANT: You must first use discover_paid_api to find an endpoint. Then use the endpoint_id from the discovery result.

Trust & safety:

• No wallet is configured, so paid endpoints will return payment details without executing.

• EntRoute verifies that endpoints return valid 402 responses every 10 minutes, but does not guarantee response quality or accuracy.
