With our APIs, we provide you with a convenient way of integrating our know-how into an external software solution, starting at just € 0.01 per query.

Our APIs comply with the XML standard so that you can address them from almost all systems and platforms. In addition, we provide a free DLL file for direct referencing for .NET developers.

Should you require additional output formats, we will be happy to provide them on request, also tailored to your individual needs.

With our APIs, we are continuing our tradition of creating a sensible product for the public from a product developed out of our own necessity.

You need an API that we don't offer yet? Contact us without any obligation and tell us your needs and we take care of building that API.
