  title: "AI Crawler Index"
  version: "2026-09-03"
  summary: "Every AI crawler on the web, what it is for, what blocking it costs you, and the IP ranges its operator publishes — as JSON, CSV, robots.txt and regex."
  description: |-
    A read-only, static, keyless index of 150 web crawlers operated by 74 companies and projects: what each one is for, the exact robots.txt token and user-agent substring, whether the operator says it obeys robots.txt, how to verify it is genuine, and — the part nobody else publishes — what you lose by blocking it.

    Every path below is a static file. There is no key, no rate limit and no state; `Access-Control-Allow-Origin: *` is set, so it is callable from a browser. Data is CC0.

    The IP-range mirrors are refreshed from 15 operator-published endpoints; /status.json reports when each was last fetched and whether it changed.

      description: |-
        A since-cursor feed of every real change to this index: operator IP-range lists that gained or lost prefixes, upstreams that started or stopped answering, and crawler records added, edited or withdrawn.

        Read `cursor` from the response and send it back as `since` next time. The cursor is a monotonic integer that only advances when something actually changed, so an unchanged answer is proof of nothing new — not a coincidence of timing. An empty page is about 2.5 KB; sending the response's ETag back as `If-None-Match` makes it a 304 with no body at all.

        The 15 upstream endpoints are re-fetched every six hours, so polling faster than that returns the same cursor. Nothing is rate limited; the request is simply not worth your budget.

        `stale_sources` is repeated in EVERY response, including empty ones: when an upstream fails, this host keeps serving its last good prefixes rather than an empty list, and a client that polls daily should not have to have been listening at the exact minute it broke to find out.

        Takes no arguments at all. It answers about the request you just made: the user-agent you sent, the address you came from, whether the crawler index recognises you, whether any operator publishes a prefix containing your address, the class this host's own instrument books you as, and whether we have seen you here before and what you fetched. Every fact comes from your own request headers or from a file this host already publishes; nothing is fetched and nothing about you is invented.

        No account, no key, no handshake. This endpoint takes no parameters at all: a bare GET is the whole call and returns the real answer. Add ?spec=1 for the specification instead. It is the one call you can make here before you know anything about this host. This endpoint holds no copy of the logic: it calls the `whoami` MCP tool at https://www.pathwren.workers.dev/mcp in-process, through that server's own JSON-RPC envelope. One implementation, two doors.
