Zillow's proprietary automated home valuation estimate, the most recognized AVM among consumers. API access restricted to approved Bridge Interactive partners.
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.
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.
In October 2025, Zillow launched Zillow Pro ($138/month), an agent product combining Follow Up Boss CRM, My Agent placement, and enhanced Agent Profiles -- this is NOT a data API but represents Zillow's push into agent tools. A limited consumer affiliate program exists through Sovrn Commerce (VigLink) and Yeesshh for driving traffic to zillow.com, but it is low-value CPA and not significant for data-focused content.

Questions every Zillow API shopper asks.
Is there a public Zillow API in 2026?
No. The old Zillow Web Services API is deprecated. Current API access is invite-only through Bridge Interactive (bridgeinteractive.com). Contact api@bridgeinteractive.com with a legitimate business case to apply. There is no self-serve developer program.
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.
What is Zillow Pro?
Zillow Pro is a $138/month agent product launched in October 2025 that combines Follow Up Boss CRM, My Agent placement on Zillow listings, and enhanced Agent Profiles. It is NOT a data API -- it is an agent productivity and lead management tool. Zillow Preferred partner agents get free access through 2026.
Who is Zillow's CEO in 2026?
Jeremy Wacksman became CEO of Zillow Group in August 2024, succeeding co-founder Rich Barton who stepped back from day-to-day leadership. Zillow Group (NASDAQ: Z, ZG) has approximately 8,000+ employees headquartered in Seattle, Washington.
Does Zillow have an affiliate program?
Zillow has a limited consumer affiliate program through Sovrn Commerce (VigLink) and Yeesshh for driving traffic to zillow.com. It pays low CPA (cost per action) commissions with approximately 30-day cookies. This is NOT a data API affiliate program and is not a significant revenue opportunity.
What alternatives exist for Zillow data access?
ATTOM Data Solutions offers the most developer-friendly property data API with RapidAPI availability and flexible pricing. Cotality (formerly CoreLogic) provides enterprise-scale data with 99%+ U.S. coverage. Redfin Data Center offers free market-level data. Bridge Interactive remains the only legitimate path for Zillow-specific data.
