Is there any documentation or sources on how they build their apis and authorization layer? It seems that its pretty consistent and follows conventions in generating:

- Generated cli tools

- Generated client libraries

- Documentation for said libraries

- Conventions for endpoints and hosting

- Authorisation via policies

Also they seem to follow an RPC style convention. Any leads on a framework that does exactly this in a consistent way so you can build your own kind of services in a similar manner

Thank you
