Sometimes, all you need is the data. This is the simplest possible wrapper I could make. It returns decoded JSON, with some fat trimmed. It should stay out of your way.
Usage:
>>> from sunlight import Sunlight
>>> sunlight = Sunlight(API_KEY)
>>> pelosi = sunlight.legislators.get(lastname='pelosi')
>>> print pelosi['firstname']

This should work with any method on Sunlight' Congress API defined here: http://services.sunlightlabs.com/docs/Sunlight_Congress_API/
See test.py for more details and examples.
