I need an API request which lists of user names of all users who did an

Is that somehow possible? Sadly the "Active Users" do not provide a
possibility for a range / starting date. Or is this a configuration
within the LocalSettings?

You can just loop through the list of all files/revisions by date and collect usernames. For a more efficient approach, you need to write your own SQL query. For Wikimedia projects, you can use Quarry.
