Bridge

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.

Bridge publishes 11 APIs on the APIs.io network, including Agents API, Listings API, Media API, and 8 more. Tagged areas include Real Estate, MLS, RESO, Listings, and Property Data.

The Bridge catalog on APIs.io includes 1 JSON-LD context and 1 Spectral governance ruleset.

Bridge’s developer surface includes authentication, developer portal, documentation, getting-started guide, sandbox, signup flow, changelog, and 24 more developer resources.

  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.
