Fanspeed, Position extruder data in Python with REST API

What is the problem?

I cannot manage to get the current fanspeed, feedrate and position of the extruder head with REST API in Python. I read on some forums that this is not possible but I was wondering if there is any other/new way to get this data. The goal in the end is to collect as many printer variables as possible while printing to do some analysis.

What did you already try to solve it?

I managed to get the temperature data of the extruder and the bed with REST API and I can post commands for the fanspeed for example.

I use Octoprint with my laptop connected to a Prusa MK3s

This is actually covered in the very documentation of the API endpoints:

The listen sub command is a basic push socket client that simply logs what it receives. The socket client is implemented in octoprint_client.Client#create_socket.
