PerplexityBot is Perplexity AI's crawler. It fetches web pages so Perplexity's answer engine can cite and summarise live sources in response to user queries.

At a glance

Operator: Perplexity
Type: AI Search
RSL category: ai-input

How Centinel checks it

User agent: The request calls itself this crawler. Anyone can send the same string.
IP ranges: The operator publishes the addresses it crawls from, and Centinel checks the client address against that list.

A request that passes one of these checks is PerplexityBot itself. One that only matches the user agent is reported as unverified. The match tokens, verification domains, and address feeds are not published here.

Allowing or blocking it

The crawler object in the /validate response sets access_allowed to true only for a verified source that your tenant allowlists. A policy rule can allow or block this crawler by its category, AI Search.
