Bridge (Bridge Interactive / Bridge Data Output) is a Zillow Group company that runs the Bridge Platform — a RESO Platinum-certified MLS data distribution service used by Multiple Listing Services and brokerages across the US and Canada. The Bridge RESO Web API exposes normalized listing data (Property, Member, Office, OpenHouse, Media, Room, UnitType) via OData 4.0 at api.bridgedataoutput.com/api/v2/OData, with a parallel native Bridge Web API serving the same resources as flat JSON. A Webhooks API delivers real-time listing change events with PKI-signed payloads. Bridge also distributes Zillow Group Data — parcels, assessments, and ZHVI/ZORI economic feeds — through the same API surface.
