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 25 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Securities & Market Data regime (on an ambiguous tag, where no other regime matched), so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/bridge-mls: open an issue to ask a question, or submit a pull request to add artifacts.

  data:
  - RESO Platinum-certified Web API serving normalized MLS listing data across the US and Canada
  - OData 4.0 query surface with $filter, $select, $expand, $orderby, $top, $count plus Bridge unselect extension
  - Resources include Property, Member, Office, OpenHouse, Media, Room, UnitType, and other RESO-defined entities
  - Both v2 (api.bridgedataoutput.com/api/v2) and v3 (api.bridgedataoutput.com/api/v3) endpoints
  - Native Bridge Web API serving the same resources as flat JSON for non-OData consumers
  - Webhooks API for real-time listing change events with PKI-signed payloads and exponential-backoff retries
  - Server Token and Access Token authentication scoped per dataset
  - Data refreshed every 10 minutes or less per MLS feed
  - Media returned as embedded object on Property records, CDN-hosted at highest available resolution
  - Off-market and historical data available where licensed by the MLS
  - DataSystem endpoint to discover dataset capabilities and metadata
  - $metadata endpoint exposes the OData CSDL schema per dataset
  - maxpagesize header (default 10, max 200) controls page size — Bridge interprets $top as page size, not total
  - Zillow Group Data feeds (parcels, assessments, ZHVI/ZORI econ data) on the same API surface
  - Parity Plus program lets MLSs customize the API the way they would with RETS
  - Preparing datasets for RESO Data Dictionary 2.0 certification
  - Public API Explorer with a test dataset for evaluation

description: 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.
