API to access class information

What I want:

      I have seen the API system is planned to be decommissioned in the next months. I would like to ask if there is a workaround or a standard procedure to download the students information: Name, username and email. I would also like to have a programmatic way of downloading their reports, including batches (names and amount per each), energy points gained per exercise (regardless of that being an exercise assigned by me or else), assignment info, time spent working per day and the like. All that information was previously available at least in 2018.

     This is very important to gamify my classroom. What I intend to do is to download the information and process it with Python scripts to translate their achievements in Khan Academy to benefits in my classroom.  I wrote some of these scripts for a previous version of the Teacher Dashboard, where many different csv files were available,  but now I cannot find where to find those reports.

What I have found and tried:

   I have seen that under the configuration section of the class, what makes no sense for me, it is possible to download a csv file only with information about the exercises that have been assigned to the class, what is very useful but incomplete for my use.
