SAP CDS/ CAP API Reference & Documentation

[Mowkax]

Hello,

Is there a detailed documentation of interfaces provided by  "sap/cds" package?
Me and my teammates are struggling to find detailed API Reference for CAP for quite a long time already.
The only resource available is https://cap.cloud.sap/docs/, but it does not provide enough information on CAP class methods, method return types etc. Without such documentation developer has to either go into source code of the npm package, or spend A lot of time debugging and testing ootb interfaces to understand what they can & can not do.
If anybody knows a page with detailed reference of each API provided by CAP - kindly share it, it will be much appreciated.

Here's an example of such documentation - API reference for MongoDB Node.js driver.
