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.

normalized to the RESO Data Dictionary. Resources include Property, Member, Office, OpenHouse,
Media, Room, UnitType, and other RESO-defined entities. Supports $filter, $select, $expand, $orderby,
$top (page size), and $count OData query options, plus Bridge extensions like the unselect parameter
and the maxpagesize header (default 10, max 200). Data is refreshed every 10 minutes or less per
MLS feed. Bridge is preparing datasets for RESO Data Dictionary 2.0 certification.

flat JSON. Provides a simpler request/response shape than the OData endpoint while preserving RESO
Data Dictionary field naming. Media is returned as an object on the Property record and is hosted
on a CDN. Requires a server token or access token issued by Bridge per dataset.

create/update/delete and other dataset changes, eliminating the need to poll the Web API. Endpoints
require an HTTPS URL with a valid X.509 certificate; Bridge issues a PKI public key (PEM) for
payload signature verification. Events are delivered as application/json; endpoints must respond
200 quickly. Failed deliveries are retried with exponential backoff for up to two days. Webhooks
begin in a disabled state for testing before activation.
