Realtor.com Data Extraction
Extract publicly available data from Realtor.com at scale using AlterLab's API — JavaScript rendering, structured extraction, and automatic retries in one request.
Website Compatibility Notes
Realtor.com uses moderate bot protections with JavaScript-required property data. Property detail pages load listing status, price, and agent information dynamically. Rate limiting applies at the IP level for high-frequency requests. Geographic restrictions mean US residential proxies improve reliability.
Technical Context
Realtor.com property URLs use an address-based slug pattern. Search pages are parameterized by geography and filters. Realtor.com is operated by News Corp and aggregates MLS listings — the data is generally more current than Zillow for newly listed properties. The MLS number on property pages is a useful cross-reference identifier for data verification.
