As I develop the features further, the internal API structure and authentication mechanism is constantly changing.
Providing public access at this point in time would either create a lot of frustration as developers will need to continuously patch their applications for changes, or would slow down the development process as I would not be able to optimize database tables/structures freely if I have to support multiple versions in a backward compatible manner.
I plan on being able to reach a somewhat stable API base in a few months, however my IRL work has been keeping me very busy with only limited time on the weekends to further all the development efforts across active feature sets.
tl;dr - This is not available now, but will be in the future.
