Limits & privacy

Only public HTTP/HTTPS targets on ports 80, 443, 8080, or 8443. Private, loopback, link-local, and reserved IP ranges are blocked on every hop. Up to five redirects, 256 KiB response data, and a ten-second overall deadline. No cookies or user credentials are sent. The certificate probe can inspect invalid certificates but sends no application data. It does not weaken TLS verification for other requests.

Use this tool from the API reference or connect through the SDK, CLI, SSH, or MCP. Hosted calls share your plan allowances.
