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

/tools/verification-methods?crawler=openai
How do I prove a request really is one of OpenAI's crawlers? Every crawler OpenAI operates in one call, each with the verification method that operator publishes for it.
/tools/verify-crawler?ip=132.196.86.0&ua=GPTBot
Is 132.196.86.0 really GPTBot? 132.196.86.0 is the first address of 132.196.86.0/24, from the GPTBot list shown on this page. The call checks it against every prefix this host mirrors.

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.
