Zillow's proprietary automated home valuation estimate, the most recognized AVM among consumers. API access restricted to approved Bridge Interactive partners.
Z
Zillow API
zillow.comZillow API provides invite-only access to property data, Zestimate valuations, and listing information through Bridge Interactive for approved real estate technology partners.
The verdict
Zillow's brand recognition is unmatched and Bridge Interactive provides legitimate data access for approved partners, but the invite-only model means most developers should look to ATTOM for accessible property data APIs or Cotality for enterprise-scale solutions.
01 — Overview
What Zillow API is, and isn't.
Zillow Group (NASDAQ: Z, ZG) is the most recognized consumer real estate brand in the United States, and their data products -- including the famous Zestimate home valuation -- have become household names. Under new CEO Jeremy Wacksman (since August 2024, succeeding co-founder Rich Barton), the company has been expanding its agent-facing products while maintaining restricted data access.
API access to Zillow data is significantly more restricted than many developers expect. The primary path is through Bridge Interactive (bridgeinteractive.com), which provides invite-only access to Zillow Group data including public records for 148M properties across 3,200 U.S. counties. Bridge Interactive does not charge service fees; license agreements are between developers and data providers. Approximately 20 APIs are available across Zillow Group brands (Zillow, Trulia, StreetEasy). The old Zillow Web Services API is deprecated.
Zillow Pro is now available nationwide as an agent membership combining Follow Up Boss CRM, My Agent placement, and enhanced Agent Profiles. Zillow does not publish a fixed price; pricing varies by number of users and requires contacting sales. This is not a data API. Sovrn Commerce lists an active Zillow merchant program, but the public listing does not disclose commission or cookie terms.

Can I get Zestimate data via API?
Zestimate API access requires approval through Bridge Interactive. Unofficial third-party services on RapidAPI claiming to provide Zestimate data typically violate Zillow's terms of service and should not be relied upon.
