Real Estate Analytics API
Build real estate market intelligence tools by extracting listing prices, property attributes, rental comparables, and neighborhood-level data from public property portals.
How It Works
Define the target market
Select geographic areas, property types, and price ranges to scope the extraction against specific search result pages.
Extract listing data
Pull property price, square footage, beds/baths, days on market, price history, and agent details from listing pages.
Build market models
Aggregate extracted data into price-per-sqft matrices, rental yield calculators, and supply-demand trend models.
