If you've tried to access the Zillow API recently, you've likely run into a wall. Zillow deprecated their public API in 2021 and replaced it with Bridge Interactive, an enterprise-only platform that requires a lengthy application process, a real estate industry affiliation, and months-long approval timelines.
For individual developers, startups, and data analysts who just need property data, this is a dealbreaker. The good news: several strong Zillow API alternatives have emerged. Here's how they compare.
What Happened to the Zillow API?
Zillow's original public API gave developers free access to Zestimates, property details, and search results. In 2021, Zillow shut down the public API and transitioned to Bridge Interactive, which is designed for MLS-connected platforms and real estate businesses, not individual developers.
To use Bridge Interactive, you need to:
- Apply through Zillow Group and justify your use case
- Wait weeks to months for approval
- Sign an enterprise agreement with restrictions on data usage
- Pay enterprise-level pricing (typically $500+/month)
If you're building a side project, investment analysis tool, or proptech startup, this isn't practical. Here are the alternatives.
The 5 Best Zillow API Alternatives in 2026
| Provider | Starting Price | Free Tier | Setup Time | Data Source |
|---|---|---|---|---|
| APIllow | $0.003/result | 50 req/month | Instant | Zillow (live) |
| ATTOM Data | $95/month | Trial only | 1-2 days | MLS + public records |
| Estated | $0.10/call | None | Instant | Public records |
| Bridge Interactive | ~$500/month | None | Weeks-months | Zillow/MLS |
| RapidAPI scrapers | $0.002-0.01/call | Varies | Instant | Zillow (scraped) |
1. APIllow
Best for: Developers who want Zillow-specific data without enterprise contracts.
APIllow is a dedicated Zillow property data API that returns 50+ structured fields per property, including Zestimates, price history, tax records, school ratings, agent info, and comparable properties. You can search by city, ZIP code, street address, Zillow URL, or property ID.
What makes it practical:
- Free tier with 50 requests/month, no credit card required
- Instant API key — sign up and start making requests in under a minute
- Pay-as-you-go at $0.003 per result ($9.99/mo for 3,333 requests)
- Simple REST API with one primary endpoint
- MCP server for AI agent integration (Claude, Cursor, etc.)
2. ATTOM Data
Best for: Enterprise users who need comprehensive public records data beyond just Zillow.
ATTOM aggregates data from public records, MLS feeds, and tax assessors across the US. Their coverage is broad: property characteristics, ownership, mortgages, foreclosures, environmental risk, and more. However, they don't have Zestimates (that's Zillow-proprietary) and their starting price of $95/month is designed for businesses, not individual developers.
3. Estated
Best for: Property characteristics and ownership data from public records.
Estated provides a clean API for property details sourced from county assessors and public records. It's solid for basic property attributes (beds, baths, sqft, year built, owner info) but lacks Zillow-specific fields like Zestimates, listing agent info, and user engagement data. At $0.10 per API call, it's also significantly more expensive per request than Zillow-sourced alternatives.
4. Bridge Interactive (Official Zillow)
Best for: Real estate businesses with MLS connections and enterprise budgets.
If you're building an MLS-connected real estate platform and can justify the application process, Bridge Interactive gives you official access to Zillow Group data. The data is comprehensive and comes with legal clarity. The downsides: long onboarding, restrictive terms, and pricing that starts around $500/month.
5. RapidAPI Marketplace Scrapers
Best for: Quick testing and comparison shopping between providers.
Several Zillow scraping APIs are available on the RapidAPI marketplace, including APIllow. The marketplace makes it easy to test multiple providers side-by-side with a unified billing system. Pricing ranges from $0.002 to $0.01 per call depending on the provider and data coverage. Quality varies significantly — check recent reviews and test with your specific use case before committing.
How to Choose
The right choice depends on your use case:
- Need Zillow-specific data (Zestimates, listing agents, price history)? Use APIllow or a RapidAPI scraper.
- Need public records (ownership, mortgages, tax assessments)? Use ATTOM or Estated.
- Building an MLS platform with enterprise backing? Apply to Bridge Interactive.
- Want to start building today with no approval process? APIllow has a free tier with instant signup.

Is the Zillow API still available?
Zillow's original public API was deprecated in 2021. The replacement, Bridge Interactive, requires enterprise approval and is not accessible to individual developers. Third-party APIs like APIllow provide access to Zillow property data without the approval process.
Can I still get Zestimate data via API?
Zestimates are Zillow-proprietary valuations. The only way to access them via API is through Zillow's official channels (Bridge Interactive, with enterprise approval) or through a third-party API like APIllow that extracts them from Zillow listings.
What's the cheapest way to get Zillow data?
APIllow offers a free tier with 50 requests/month. Paid plans start at $9.99/month for 3,333 requests ($0.003 per result). This is significantly cheaper than ATTOM ($95/month minimum) or Estated ($0.10/call).
