Does Zillow have a public API? Not the open one developers remember. Zillow retired its public API (ZWSID) in 2021; today, official access runs through Bridge Interactive and is gated behind MLS membership and a multi-week approval. If you just need structured U.S. property data in your app now, third-party APIs fill that gap. Zillapi is one: a productized Zillow Data API that returns 300+ fields per home — price, Zestimate, photos, schools, taxes, full price history — across 160M+ U.S. parcels, in one REST call. No scraping, no proxy farm. Start free with 100 credits, no card.

Does Zillow have an API? (the 2021 shutdown and what replaced it)

The original Zillow Web Services API (ZWSID) — the one behind old tutorials and the dead ZillowR package — was shut down in 2021. Since then there has been no open, self-serve public Zillow API. What exists in 2026:

  • Bridge Interactive (a Zillow Group company) is the official route to Zillow Group data. It’s real and licensed — but it’s built for MLS-affiliated and enterprise use: expect MLS membership or vendor approval, data-use agreements, and a multi-week onboarding before your first call.
  • Third-party property-data APIs (Zillapi and others) give developers same-day, self-serve access to Zillow-sourced property data without the MLS gate.
  • Scraping Zillow directly still happens, but Zillow’s terms restrict automated access, and scrapers break constantly against anti-bot defenses and a changing DOM (see below).

How to get Zillow API access in 2026

There are three practical routes, and they trade off speed against licensing:

  1. Official (Bridge Interactive) — the right path if you specifically need licensed MLS data with contractual guarantees, and you can clear membership/vendor approval and a weeks-long onboarding.
  2. A productized third-party API (Zillapi) — sign up, get a zk_ key, and make your first call in minutes. 100 free credits at signup, no card. Best fit if you need current U.S. residential property data on demand and don’t need a licensed MLS feed.
  3. DIY scraping — no signup, but you own the anti-bot arms race, the proxy costs, the broken selectors, and the terms-of-service risk. Most teams that start here migrate to an API once maintenance eats the savings.

For most developers and AI-agent builders, route 2 is the fastest path from idea to data.

What does the Zillow API cost?

It depends entirely on the route:

  • Bridge Interactive: quote-based/enterprise — no public self-serve pricing; cost is scoped to your license and volume.
  • Zillapi (credits): pricing as of Jul 2026 — Free ($0, 100 credits at signup, no card), Monthly ($5/mo, 1,000 credits), Annual ($54/yr, 12,000 credits upfront). Most calls are 1 credit per record; address-based lookups are 3 credits; search returns up to 50 results at 1 credit each; failed calls are free. See pricing for the full breakdown and top-up rates.
  • Scraping: “free” until you price in proxies, captcha-solving, engineering time, and breakage — usually the most expensive option once it’s running at scale.

Can you legally pull data from Zillow?

Zillow’s terms restrict automated scraping of its website, which is why a sanctioned data route matters. Using a productized API means you call a documented endpoint and get structured JSON back — no scraping of Zillow.com, no ToS gray area to manage yourself. Zillapi handles proxy rotation, captchas, schema normalization, retries, and 24-hour caching so your integration stays clean and stable.

How to pull Zillow property data with Zillapi

One REST call returns structured JSON your app — or your AI agent — can act on directly. Base URL https://api.zillapi.com/v1, authenticated with Authorization: Bearer zk_...:

Terminal window
# Single property by its Zillow URL (1 credit per record)
curl https://api.zillapi.com/v1/properties/by-url \
  -H "Authorization: Bearer $ZILLOW_API_KEY" \
  --data-urlencode "url=https://www.zillow.com/homedetails/17-Zelma-Dr-Greenville-SC-29617/11026031_zpid/" -G

You get back price, Zestimate, rent Zestimate, beds/baths, photos, schools, tax history, and full price history — 300+ fields, one round trip. Need just one field? Sub-resources like /{zpid}/zestimate and /{zpid}/tax-history return exactly that. Building an AI agent? The same data is available through Zillapi’s live MCP server at api.zillapi.com/mcp (same key) — see For AI agents. Start at the Quickstart to make your first call in 60 seconds.
