Douglas Elliman Inc. (NYSE: DOUG) is a residential real estate brokerage founded in 1911 and headquartered at 575 Madison Avenue, New York City. It is one of the largest brokerages in the New York metropolitan area and among the largest in the United States, with roughly 6,000 agents across New York, Florida, California, Texas, Colorado, Massachusetts, Connecticut, Nevada, New Jersey, Vermont, the Mid-Atlantic, and international outposts in France and Monaco. Its home market is the United States. In the value chain Douglas Elliman sits on the SELL side as a licensed brokerage and MLS participant — it consumes MLS listing data under IDX and broker agreements rather than originating a syndicated feed — and it extends into development marketing, property management, commercial brokerage, title and escrow (Douglas Elliman Title), relocation, and PropTech venture investment through New Valley Ventures. Its API posture is honest and thin: no developer portal, no published API documentation, no OpenAPI or OData $metadata contract, and no published access path of any kind. developer.elliman.com, developers.elliman.com, and docs.elliman.com all resolve to the marketing homepage via a wildcard catch-all rather than to a portal, and api.elliman.com exists as an IIS/ASP.NET host that returns HTTP 403 at its root with no documentation behind it. On RESO, Douglas Elliman Real Estate is listed as a Class D member (Brokers, Agents and Appraisers) on the RESO membership roster but does NOT appear in the RESO certified-organizations directory — it is a RESO member, not a RESO-certified data provider, and it publishes no Web API or Data Dictionary certification, no OData endpoint, and no UPI surface. The single public engineering artifact the company ships is a GitHub fork of a third-party .NET RETS client library, which is consumer-side evidence that Elliman pulls MLS data in rather than producer-side evidence that it exposes any.
