Open API (+docs)

[MaxSemenchuk]

API docs will be autogenerated for us, will look something like this: https://app.trpcpanel.io/

We will support the OpenAPI standard, so anyone can consume the API easily, and we will have fully e2e typesafe APIs for Typescript, React, React Native etc.

an SDK might be in order

I would put this in the main repo, not to fragment things too much. A single source for all technical info.
