It describes itself, inside its own user-agent, as bingbot/2.0. That is the client's own words, quoted; this page makes no claim about what it is for.

The crawler catalogue on this site has a record for it: /crawler/bingbot.html — what it is for, and what blocking it costs. This page is only what it did here.

Our instrument classed it
crawler×177 — that is our classifier's label from the user-agent, not the operator's, and it has been wrong before.

How to verify it is really them

published IP ranges The published ranges we mirror for it are at /ip-ranges/bing-bingbot.html.

From the crawler record at /crawler/bingbot.html, which cites https://www.bing.com/webmasters/help/which-crawlers-does-bing-use-8c184ec0 — one source for both pages.

Ask this page a question, with one GET

A question about this page, answered by a call you can make right now — no key, no account, no JSON-RPC, nothing to assemble. The query string is already filled in with this page's own subject.

curl -s 'https://www.pathwren.workers.dev/tools/classify-ua?ua=Mozilla%2F5.0%20AppleWebKit%2F537.36%20%28KHTML%2C%20like%20Gecko%3B%20compatible%3B%20bingbot%2F2.0%3B%20%2Bhttp%3A%2F%2Fwww.bing.com%2Fbingbot.htm%29%20Chrome%2F116.0.1938.76%20Safari%2F537.36&s=client-dossiers'

Every parameter above is a value the endpoint reads, not an address it visits: nothing is fetched on your behalf. Called without any parameter, each endpoint returns its own specification instead of an error. All of them.

What it publishes about you afterwards

Not observed. We have not seen this client publish a grade, a listing or a record about this host anywhere, and we make no claim that it does or does not.

Its own documentation

It names http://www.bing.com/bingbot.htm in its own user-agent. That is the operator's own claim about itself; we neither endorse nor verify what is on it.

Method, and what this page will not say

Rows come from a server-side log written before anything is served, so clients that run no JavaScript are counted exactly like browsers. The window is the whole life of the log, 2026-08-31 20:58:11Z to 2026-09-14 05:57:10Z UTC, and it is stated on every number because a count without a window is not a fact. Addresses are stored as salted hashes and counted, never printed. Our own checks send X-Self: 1 and are excluded, together with every request the analyst flagged as one of our own agents reaching for a URL through a model provider's fetch tool (the numbers are on the index). Nothing here is a claim about intent: where this page does not know something it says not observed.
