We offer more than 20 public REST APIs around real estates, real estate market data, geo services, realtor data and much more. Check "Our APIs" for getting an overview on the APIs. "Getting Started" not only leads you to the registration, but also contains faq, basic principles, playground, sandbox and much more. Before you start coding, please first check whether there's an SDK available for your programming language and view the tutorials on the same page. We offer technical support by email (firstname.lastname@example.org) and by public forum. Feel free to give us feedback!
We will block the „Vollabgleich“ use case (regularly deletion and upload of the same real estates and attachments) from 01.11.2015.
