API description?

Hi,
I just wonder if there is a description of the API available somewhere.
I plan to integrate support for USB-UIRT into the OpenAPC (Advanced Process Control) Software which can be used for professional and home automation tasks. For the last one USB-UIRT would a perfect solution.
On the website I could not find a description of the programming interface - so where can I get it from?
