Zillow (Bridge API) vs Repliers API 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. Repliers API is a real estate data API that connects to US and Canadian MLSs and serves their listings through one REST API, with AI search features and an official MCP server.
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.
- Repliers API: Licensed agents and brokerages who want an AI-ready, MCP-connected API on top of their own MLS feed.
