ClaudeBot

What this client asked www.pathwren.workers.dev for, when, and what it got. Every number below is from this host's own server-side request log, 2026-09-01 00:46:32Z to 2026-09-01 06:15:19Z UTC.

Mozilla/5.0 AppleWebKit/537.36 (KHTML, like Gecko; compatible; ClaudeBot/1.0; +claudebot@anthropic.com)

504 request(s) from 2 distinct address(es), 368 distinct path(s), first seen 2026-09-01 00:46:32Z, last seen 2026-09-01 06:15:19Z UTC. 5 separate visit(s), counting a gap of more than 30 minutes as a new one, median 62.2 minutes between them.

It describes itself, inside its own user-agent, as ClaudeBot/1.0. 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/claudebot.html — what it is for, and what blocking it costs. This page is only what it did here.

Our instrument classed it

agent×504 — 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

no published verification method

From the crawler record at /crawler/claudebot.html, which cites https://support.anthropic.com/en/articles/8896518 — one source for both pages.

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 mailto:claudebot@anthropic.com 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, 2026-09-01 00:46:32Z to 2026-09-01 06:15:19Z 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.
