API
There is no public API yet.
We would rather say that plainly than publish a page describing one that does not exist. When it ships it will be documented here, with authentication, rate limits and per-endpoint reference.
What exists
Internal endpoints serve the application and are not supported for external use — they change without notice and are not versioned.
If you have a specific integration need, tell us. It is more useful to build against a real requirement than to guess.
