The Realtor.com Data API provides structured access to US residential property data. Search homes for sale, for rent, and recently sold, retrieve complete listing detail and automated valuations, and pull agent, school, mortgage, and market intelligence through clean JSON endpoints.
What You Can Access
Search is the deepest part of the API. /search covers for-sale, for-rent, and sold homes with a filter surface of roughly 97 parameters - price, beds, baths, square footage, lot size, year built, property type, HOA fees, days on market, keywords, open houses, price reductions, foreclosure status, pet policy, and dozens more. Dedicated /properties-for-sale, /properties-for-rent, and /properties-sold endpoints expose the same surface scoped to one status, and /property-search widens the net to the full property universe including off-market and public records.
Geographic search is available four ways: radius around a coordinate, a custom map polygon, a commute-time isochrone from a point, and a pasted Realtor.com search URL. /locations-autocomplete resolves free text to the location slug IDs and centroids those searches take, and /map-boundary returns the GeoJSON polygon for a ZIP, city, neighborhood, or county.
Property detail is available by ID, by listing URL, or directly from a street address, with /similar-homes returning comparables and /property-environment returning flood, wildfire, heat, wind, air, and noise risk scores. /property-valuation returns the RealEstimate automated valuation for a property across every AVM source it carries, with historical values and a forward forecast.
Agent endpoints cover the directory with true match counts, full profiles including licence, languages, specializations, and brokerage, plus reviews, recommendations, a merged feedback feed with verification flags, and an agent’s listings by status. School coverage includes search by city, ZIP, county, or neighborhood, single school lookups, and district records with enrolment and ratings.
Mortgage and market data round out the API: current average rates by loan type for a ZIP, a payment calculator, a live lender rate table, market hotness scores, neighborhood guides, geo statistics with median list, rent, and sold prices, and a market feed of new listings, open houses, and price drops.
