Can you move this into the backend? This type of functionality should not be exposed in the API layer.

getDataDims() is already available as a method to C-API. Whats the need to call it in the backend? It's just going to add redundant code.

There is a logical separation between the api and the backend codes. The api calls should not implement any functionality. It should only expose the backend state to the user.

This file is located misleadingly. This should have ideally been under src/backend/internal.cpp. All backends use this file internally so this is technically part of the backend code, not the api code.
