Your search through API docs was effective, there indeed isn't a
dedicated API call for that :-) The information is stored within
project properties and you can read the enabled state like this:
QgsProject.instance().readBoolEntry("ScaleBar", "/Enabled", False)
This will return a tuple (is_enabled, success) where the first value
is the value you are looking for, the second one just tells whether
the reading of the project property was successful.
Hope that helps!
Cheers
Martin
