Are there some docs about this endpoint? I have searched API docs but it is not there.

Just this post: Creating a staged user with an API call

I am looking for a way how to create topic and assign it to a specific user (by discourse-assign plugin).

This is totally doable. Have a look at How to reverse engineer the Discourse API and you will see which endpoint the discourse-assign plugin calls.

And also thinking if API key have to by for user system or I can use some other user with minimal permissions (what are that minimal required?).

Nope does not need to be with the system user. You just need a user with enough trust level to create and assign topics.
