Keep getting "bad request"

[guysoft]

Hey,
I am trying to get this library to work.
I have managed to create an access token, as provided by the readme (got a code, then an access token).
The reply looks like this:
{u'access_token': u'TOKEN_GOES_HERE', u'token_type': u'Bearer', u'expires_in': 31536000, u'refresh_token': u'REFRESH_TOKEN_GOES_HERE'}

But any call I make gives me "bad request"
Example:
jb.api_call("TOKEN_GOES_HERE",'nudge/api/v.1.1/users/@me/moves')

returns:
{'status_code': 400, 'error': 'Bad Request'}

What could I be doing wrong?
