Zillapi
US property data API — Zestimate, photos, taxes, price history.
About Zillapi
Zillapi is a REST API that provides structured U.S. property data sourced from Zillow, covering over 160 million parcels across every state and metro area. A single call returns more than 300 fields per property, including address, price, Zestimate, rent estimate, bedrooms, bathrooms, lot size, year built, taxes, schools, agent contact, photos, and full price history. The API also offers nine sub-resources for retrieving specific data slices such as photos or price history without pulling the full record, along with endpoints for property search by bounding box or Zillow URL, building extraction, async batch jobs, and signed webhooks for job completion.
The service is built for developers and AI agents, exposing an OpenAPI 3.1 specification compatible with tools such as Postman, Cursor, Claude, ChatGPT, LangChain, n8n, Zapier, Make, Google Sheets, BigQuery, Snowflake, and Insomnia. It also provides llms.txt and llms-full.txt files for use as context in AI systems and supports function-calling integration. Output formats include JSON, CSV, and NDJSON, and the API runs on Cloudflare Workers with edge authentication and rate limiting.
Zillapi offers three pricing plans: a free tier with 100 credits at signup and no card required, a Monthly plan at $5/month for 1,000 credits with top-ups at $4 per 1,000, and an Annual plan at $54/year for 12,000 credits (released monthly) with top-ups at $3 per 1,000. Most calls cost 1 credit per record returned, address-based lookups cost 3 credits each, and failed calls are free. Zillapi is an independent service not affiliated with, endorsed by, or sponsored by Zillow Group, Inc.

Frequently asked questions
Is there an official Zillow API in 2026?
No public Zillow API exists for property data in 2026; Zillow shut down its consumer API in 2021 and current access is gated behind the enterprise-only Bridge Interactive program. Zillapi is a third-party REST wrapper that returns Zillow-sourced data via a clean HTTP API with same-day signup.
How much does the Zillow Data API cost?
Zillapi's Free plan gives 100 credits at signup with no card required; Monthly is $5/month for 1,000 credits, and Annual is $54/year for 12,000 credits released monthly. Most calls cost 1 credit per record, though address-based lookups cost 3 credits each, and failed calls are free.
How is Zillapi different from scraping Zillow myself?
Zillapi handles proxy rotation, captchas, schema normalization, retries, and 24-hour caching, exposing the result as a stable v1 REST contract with an OpenAPI 3.1 spec. Scraping Zillow directly breaks weekly due to anti-bot defenses, captcha walls, and rotating DOM structures.
Is Zillapi affiliated with Zillow Group?
No, Zillapi is an independent service not affiliated with, endorsed by, or sponsored by Zillow Group, Inc. It accesses publicly available property data through automated tools and exposes it via a stable REST API.
What platforms and tools does Zillapi integrate with?
Zillapi is plain REST with an OpenAPI 3.1 spec that works with Postman, Cursor, Claude, ChatGPT, Zapier, BigQuery, Snowflake, n8n, Make, and Google Sheets. Output formats include JSON, CSV, and NDJSON.
