Network diagnostics
Check connectivity and response latency.
This check runs on the server. Input and results are not saved as execution history; hosted allowances apply.
About Network diagnostics
Measure a public endpoint’s DNS lookup and HTTP response timings from this server.
When to use it
Get a bounded connectivity and response check.
DNS milliseconds, first-response milliseconds, status, and addressesHow to use it
- Enter an HTTP URL.
- Inspect public addresses, status, and measured timings.
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. This is a single server-side measurement, not ICMP ping or a multi-region benchmark.
Use this tool from the API reference or connect through the SDK, CLI, SSH, or MCP. Hosted calls share your plan allowances.
