## Use constraints

- URL-based tools accept only public HTTP or HTTPS destinations and block private, loopback, and local-network addresses.
- Request and inspected-resource sizes are limited. See OpenAPI for per-field limits and error responses.
- Use the catalog as the live source of prices. The server's HTTP 402 challenge is authoritative.
- Buyer credentials, wallet secrets, seed phrases, and private keys must never be sent in an API request.
