At its homepage, perplexity.ai is protected by Cloudflare. Typical approach to reach it reliably: Browser-impersonation HTTP (matched TLS). Difficulty is per-URL, so deep pages — profiles, listings, search — are usually harder.
Wants a browser-impersonation HTTP client with a matched TLS fingerprint and realistic headers.
Typical access
TLS match
Across repeated probes from different IPs this landed anywhere from Medium–Hard — anti-bot decisions weigh IP reputation, so expect the harder end from flagged datacenter ranges.
Why it didn’t pass cleanly
Bot challenge
A JS/bot challenge interstitial was served — a browser must run it.

Evidence
This is a homepage-level snapshot and can be inaccurate or out of date — anti-bot vendors update their models continuously, deep pages are usually more protected than the homepage, and difficulty is IP-sensitive: a site can read differently from a clean vs a flagged IP and even flip over time. Treat it as a directional signal, not a guarantee.
The homepage is the open front door. On a ai tools site the valuable pages behave differently — here's the plan to characterise perplexity.ai before you build.
Pricing / docs

App / dashboard
login wallThe product itself is behind login.
Find a real deep URL cheaply from the site’s robots.txt and sitemap.xml, then run each through the anti-bot checker. This is an advisory based on the category and perplexity.ai’s homepage result — detect the wall, never try to pass a login.
Detection confidence: high
