## What it asked for that did not exist

- `/agents.txt` — 404×1 — first asked 2026-09-07 12:03:04Z; still absent
- `/.well-known/http-message-signatures-directory` — 404×1 — first asked 2026-09-07 12:03:10Z; still absent, on purpose — None, and this document belongs on somebody else's host (https://www.pathwren.workers.dev/security.html)

## 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 agentprobe/0.1.0 (+https://agentprobe.org/met…?**  
  `curl -s 'https://www.pathwren.workers.dev/tools/classify-ua?ua=agentprobe%2F0.1.0%20%28%2Bhttps%3A%2F%2Fagentprobe.org%2Fmethodology%3B%20read-only%20liveness%20probe%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.


## 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.
