# Frequently Asked Questions

> 1. What is EntRoute? +
// EntRoute is a machine-first Discovery API that returns ranked, verified pay-per-request endpoints for requested capabilities.

> 3. How are endpoints verified? +
// Every endpoint is probed every 10 minutes to verify it returns a proper 402 payment challenge. Top endpoints are further tested with real paid requests to confirm they return useful data after payment.
> 4. Can I list my own API? +
// Yes! Submit your endpoint URL, verify domain ownership via DNS, and pass our 402 verification probes.
> 5. Is there a free tier? +
// The discovery API is free to query. You only pay when calling provider endpoints, and rates are set by providers.
