Zillow (Bridge API) vs Datafiniti Property Data for AI agents
Zillow Group's developer portal lists APIs such as MLS Listings (served through the Bridge Listing Output platform), Public Records and Zestimates, and the listings and public records APIs are invite-only. Datafiniti Property Data is a searchable US property database (API, portal and bulk download) that merges listing activity, tax/assessment and transaction data per property.
The short answer
- Zillow (Bridge API): Brokers and approved vendors that already have MLS relationships and want a RESO-normalized feed from Zillow's Bridge platform.
- Datafiniti Property Data: Bulk property and listing-history records for analysis and modelling, billed per record returned.
