## 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 Mozilla/5.0 AppleWebKit/537.36 (KHTML, like G…?**  
  `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%20ClaudeBot%2F1.0%3B%20%2Bclaudebot%40anthropic.com%29&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.
