How to retrieve the AI Consumption of AI Credits of the opened session

Hello

I would like to retrieve the number of ai credits consumed by the current session (main agent + subagent). Is it possible ? If yes how ? If no, is it planned ?

The issue names no file or test; begin with the SDK's opened-session entry point and trace how the current session represents its main agent and subagent. Determine whether AI credit consumption is exposed, and consider the work complete when retrieval behavior or its unsupported/planned status is clearly documented.
