So far my research has come up with:
Finsh
Asynchronous RESTful API consumer for Python. Finch is focused on remove all of the boilerplate related to consuming http based APIs and provide a high level abstraction to develop API clients.
Hammock
Hammock is a fun module lets you deal with rest APIs by converting them into dead simple programmatic APIs.
Tortilla
Wrapping web APIs made easy. Tortilla uses a bit of magic to wrap APIs. Whenever you get or call an attribute of a wrapper, the URL is appended by that attribute's name or method parameter.
