1. DIUIT API provides a rich messaging API that can be used to build real-time communication features into any application without needing your own server infrastructure. 2. It allows for features like file transfers without servers, building HTTP services into apps, resuming transfers, and custom security. 3. The API documentation and sample code are available online, and the presentation provides demonstrations of chat rooms, authentication, and sending/receiving messages in an Android app using the DIUIT API.
