At its homepage, zillow.com is protected by PerimeterX (HUMAN). Typical approach to reach it reliably: Headless browser. Difficulty is per-URL, so deep pages — profiles, listings, search — are usually harder.
Needs a headless browser that runs the site's JavaScript challenge.

Evidence
Detection confidence: medium · vendor present but served clean (passive edge, not an active challenge)
This is a homepage-level snapshot and can be inaccurate or out of date — anti-bot vendors update their models continuously, deep pages are usually more protected than the homepage, and difficulty is IP-sensitive: a site can read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 real estate site the valuable pages behave differently — here's the plan to characterise zillow.com before you build.
