How to use

This tool belongs to the “Operations” category.

  1. 1"API reference" lists the endpoints, parameters and response fields this site itself uses - copy them straight into a script.
  2. 2"Diagnostics" reports upstream availability and cache state, and shows the most recent public query records.
  3. 3When data looks off, check Diagnostics first: an upstream marked unavailable means the tools reading it are only indicative.

Device and browser checks run on your machine. Domain and IP lookups are fetched by this site from public feeds, and each query string is kept as one public record.

Frequently asked questions

Can I call these endpoints myself?

They are the same addresses this site uses, but requests are rate limited per visitor IP. Hammering them returns 429, so keep the pace down.

Why publish a diagnostics page at all?

Probe-based tools depend on upstreams that change without notice. Showing where each value comes from, and whether it answers, lets you judge a problem instead of guessing.

What do the query records show?

Only the domain or IP that was queried plus a short summary - nothing that identifies the visitor.
