Zillow Data Extraction
Extract publicly available data from Zillow at scale using AlterLab's API — JavaScript rendering, structured extraction, and automatic retries in one request.
Website Compatibility Notes
Zillow uses advanced protections with dynamic property data loading via JavaScript API calls. Property detail pages show a skeleton layout on initial load, with actual price and listing data populated asynchronously. Search result maps load listings based on viewport coordinates. Zillow's bot detection includes TLS fingerprinting and JavaScript environment checks. Full browser rendering with challenge resolution is essential — static requests receive incomplete or blocked responses.
Technical Context
Zillow property URLs include a ZPID (Zillow Property ID) that uniquely identifies each listing. The URL pattern is /homedetails/{address}/{zpid}_zpid/. Search results load properties as GeoJSON tiles based on map bounds — to collect search results systematically, you need to vary the search bounds or use the textual search. Property detail pages are React-based with lazy-loaded sections for price history and similar homes.
