Where can I find documentation for UIkit.util?

Question

UIkit

Hello! I rummaged through the entire Internet, as far as there was enough time, but I did not find the answer to the subject. The official documentation site only mentions utilities as named classes. This is not what I need.
At the moment, I'm specifically interested in what parameters the UIkit.util.ajax() function takes ?
The question is more interesting than it might seem, since UIkit.util implements very powerful functionality. Too bad it's procedural.
