curl -s 'https://www.pathwren.workers.dev/tools/verification-methods?crawler=googlebot-image&s=client-dossiers'

• /tools/verification-methods?crawler=googlebot-image
  How do I prove a request really is Googlebot-Image? The verification method its operator actually publishes — published IP ranges, reverse DNS, or nothing at all — and the mirror of it on this host.
• /tools/verify-crawler?ip=192.178.4.0&ua=Googlebot-Image
  Is 192.178.4.0 really Googlebot-Image? That address checked against every prefix this host mirrors. 192.178.4.0 is the first address of 192.178.4.0/27, one of the ranges listed on this page — so the link is a worked example that returns a match. Swap in an address from your own log.

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. All of them.
