Where is the description of the Talos API?

This is located in the API Documentation directory when the R9 Development suite is installed. From the Start menu, locate the Sealevel R9 Development folder and choose the Talos API Documentation. You may browse available classes and their members by namespace. These pages will explain the usage and API references that fully document the Talos API, including samples and descriptions of all calls.
