ATTOM provides U.S. real-estate and property data, including property, neighborhood, boundary, valuation, and market datasets. Its products are delivered through APIs, bulk/cloud data access, and related data platforms.
ATTOM exposes a documented HTTP Property Data API that requires an ATTOM-issued API key; its site also advertises an MCP Server, but no public connect endpoint or authentication mechanics were discoverable from the surfaced docs.

Sign in to the ATTOM Property API portal. ATTOM states the API Key is assigned to you by ATTOM; after you have an API account/subscription, retrieve your key from the developer portal and keep it private. If you do not yet have access, start from the Property Data API page or contact ATTOM to obtain API access.
