Yep!
The library uses a shared routine to make all of the actual calls - you can see it in action by looking at the source for say "PostMedia"
https://github.com/bear/python-twitter/blob/master/twitter/api.py#L901At line 937 we build the Twitter API request url
Lines 939 - 963 are all building the data dictionary that will become the request parameters
Line 965 is where the request is made using the current authenticated session - the return value is the raw json blob that Twitter's API sends back
So you should be able to call _RequestUrl(url, verb, data) just like any other python-twitter api call.
