## What it asked for that did not exist

Nothing.

## Verification

Not observed. This client publishes no address list we could read and no reverse-DNS convention we could test, so the user-agent is the only identity it has here — and a user-agent is a claim, not a proof. Anyone can send this string.

## 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.

- **What is Mastodon/4.6.6 (http.rb/5.3.1; +https://socia…?**  
  `curl -s 'https://www.pathwren.workers.dev/tools/classify-ua?ua=Mastodon%2F4.6.6%20%28http.rb%2F5.3.1%3B%20%2Bhttps%3A%2F%2Fsocial.uibk.ac.at%2F%29%20Bot&s=client-dossiers'`  
  This exact user-agent run through the catalogue: which crawler it is, who operates it, what the crawl is for, what blocking it costs — or an honest "not recognised" if it is nobody we know.

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.


## What it publishes about you

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.
