openapi: 3.1.0 info: title: Bridge RESO Web Agents OpenHouses API version: '2.0' description: 'RESO Platinum-certified Web API for MLS listing data, served by Bridge (a Zillow Group company). Data is normalized to the RESO Data Dictionary and queryable via OData 4.0. Bridge interprets OData `$top` as page size (default 10, max 200 via the `maxpagesize` header) and extends the spec with an `unselect` parameter that returns all fields except those listed. Each request is scoped to a `{dataset}` (the MLS dataset code) and must carry an `access_token` — either as a query parameter or via the `Authorization: Bearer` header.
