Zillow Zestimate API is one of 17 APIs that [Zillow Group](https://apis.io/providers/zillow-group/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Valuation and Property Data. The published artifact set on APIs.io includes API documentation and an API reference.

RESTful JSON API returning Zillow property, rental and foreclosure Zestimates for approximately 100 million US properties. Zillow Group documents it on its own developer portal and routes the reference and access-token issuance to the Bridge platform, a Zillow Group company, which is why the base host is bridgedataoutput.com rather than a zillow.com host. Access is invite-only through the Zillow Group Datasets agreement.
