## What blocking it costs you

You stop being indexed and cited by Perplexity, and lose the referral clicks its citations produce.

## Ask this page a question, with one GET

A question about this page, answered by a call you can make right now — no key, no account, no JSON-RPC, nothing to assemble. The query string is already filled in with this page's own subject.

- **How do I prove a request really is PerplexityBot?**  
  `curl -s 'https://www.pathwren.workers.dev/tools/verification-methods?crawler=perplexitybot&s=client-dossiers'`  
  The verification method its operator actually publishes — published IP ranges, reverse DNS, or nothing at all — and the mirror of it on this host.
- **Is 107.20.236.150 really PerplexityBot?**  
  `curl -s 'https://www.pathwren.workers.dev/tools/verify-crawler?ip=107.20.236.150&ua=PerplexityBot&s=client-dossiers'`  
  That address checked against every prefix this host mirrors. 107.20.236.150 is the first address of 107.20.236.150/32, 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.
