Headless API

How can I get started with a headless wordpress/fluentcommunity build? I want to use fluentcommunity as the backend of a mobile app. More specifically I would like to make a feed of a space filter able by topic in the mobile app. From there I'm going to drip course content into the mobile app. The actual course creation will be done in the browser by the course creator.

I'm a web developer and I have a team working with me. I saw the official mobile app and the real time messaging implementation. If anyone knows the members who created those two projects or any like it please (@) them in the reply
