Zillow has no public listing API and sits behind a commercial bot manager, so gathering property data means scraping the site through US residential IPs that read as real house-hunters, not the Press-and-Hold wall.

What works on Zillow

Zillow sits behind PerimeterX, now part of HUMAN Security, which serves the Press-and-Hold human-verification page and returns HTTP 403 when traffic looks automated. And there is no public Zillow API for general listing data, so unlike some targets there is no sanctioned shortcut: this work is scraping the public site or nothing.
PerimeterX reads several signals at once, IP type and reputation, the JA3/JA4 TLS fingerprint, HTTP/2 and header order, a JavaScript runtime fingerprint and behavioural pacing, which is why a clean US residential IP is necessary but has to be driven by something that looks like a real browser.
A residential IP clears reputation and geography and nothing else. It does nothing for a client that announces itself with a default library user-agent, drops its cookies between requests, or moves with the tell-tale regularity of a script, which is exactly what PerimeterX is built to read. US addresses matter for both access and accuracy: a request from another country is more suspicious and sometimes geo-restricted.
Scraping Zillow sits outside its terms, and that exposure is yours however good the addresses, so stay on public, non-personal fields and get real advice for any commercial work.

FAQ
That is PerimeterX, Zillow's bot manager, deciding your traffic looks automated. Blocked requests commonly return HTTP 403. A US residential IP driven by a real browser, paced like a person, is what clears it; a datacenter IP or a bare script does not.
Not a public one for general listings, which is exactly why this work means scraping the site. Plan for PerimeterX and a real-browser setup rather than a clean API call.
Rotating US residential, pinned to the state or metro you track. It passes PerimeterX's reputation checks and returns accurate local data, where a foreign or datacenter IP is both more suspicious and sometimes geo-restricted.
It sits outside Zillow's terms of service, and you own that exposure however good the IPs. Stay on public, non-personal fields and get real advice for any commercial work.
The terms that decide how Zillow treats your traffic.
Residential proxy
A proxy that routes your traffic through an IP address assigned by an internet service provider to a home connection, so requests look like an ordinary person browsing.
Geo-targeting
Deliberately choosing a proxy in a specific country, region or city so your traffic originates exactly where you need it to.
Web scraping
The automated collection of data from websites, the single most common reason people use proxies at scale.
Rate limiting
A site's cap on how many requests one source may make in a window, the most common obstacle a scraper meets.
