Spreedly Client for Node.js 
Introduction
A Node.js library for working with the Spreedly API and credit card tokenization service.
I've tried to follow the API as closely as possible. This library provides methods for the most common functionality, with additional methods in development.
All Spreedly client methods support both an optional Node.js-style
function(err, result) callback parameter, and also return a
Bluebird promise, for maximum compatibility and utility.
