Domain Group
Domain Group (Domain Holdings Australia Ltd, trading as domain.com.au) is the second of Australia's two national residential property portals, alongside REA Group's realestate.com.au, and since 27 August 2025 has been a wholly owned subsidiary of CoStar Group. Headquartered in Sydney, Domain operates the domain.com.au consumer marketplace plus commercial, agent, and developer-project brands, and sits in the middle of the Australian value chain between selling and leasing agencies on one side and buyers, renters, banks, and PropTech builders on the other. Unlike most of the real estate sector, Domain runs a genuine, self-serve public developer portal at developer.domain.com.au: a developer signs up with GitHub, Google, or email, creates a project, and is immediately granted the "Agents & Listings" and "Properties & Locations" packages, with the remaining eleven packages - Address Suggestions, Campaign reporting, Listings Management, Price Estimation, Property Enrichment, Property Package, PropertyRadar, Rental AVM, Schools Data, and Webhooks - added per project and negotiated with an account manager. Domain publishes three machine-readable OpenAPI 3.0.4 documents (latest, v1, v2) directly from its Libraries page, backs them with an OpenID Connect discovery document at auth.domain.com.au, and serves everything from api.domain.com.au behind API-key or OAuth 2.0 (client credentials, authorization code, implicit) credentials. Write access is a different gate entirely: uploading or updating listings requires sandbox sign-off by email to api@domain.com.au and written permission from the principal agent of each agency, making listing management broker-authorised even though the read surface is self-serve. Domain carries no RESO Web API or RESO Data Dictionary certification, exposes no OData $metadata document and no Universal Property Identifier - RESO is a North American NAR-driven standard with no presence in the Australian portal duopoly - and it publishes no open, unlicensed dataset; all data is licensed under the Domain Group API Terms and Conditions.
Domain Group publishes 28 APIs on the APIs.io network, including Address Locators API, Agencies API, Agents API, and 25 more. Tagged areas include Real-Estate, Australia, Property Listings, Property Data, and Valuation.
The Domain Group catalog on APIs.io includes 2 event-driven AsyncAPI specifications.
Domain Group’s developer surface includes authentication, documentation, API reference, signup flow, getting-started guide, sandbox, support, and 45 more developer resources.
