The query string is already filled in with this page's own subject. ```bash curl -s 'https://www.pathwren.workers.dev/tools/verification-methods?crawler=openai&s=client-dossiers' ``` - [`/tools/verification-methods?crawler=openai`](https://www.pathwren.workers.dev/tools/verification-methods?crawler=openai&s=client-dossiers) **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`](https://www.pathwren.workers.dev/tools/verify-crawler?ip=132.196.86.0&ua=GPTBot&s=client-dossiers) **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](https://www.pathwren.workers.dev/tools/index.html?s=client-dossiers).
