Kirk just finished putting together a new wiki detailing all of our API functions. The wiki is open to anyone that wants to submit API suggestions, requests, etc. and then track what other people are contributing to their ideas (you just have to create a username and password, first). We’re aiming to create a community around our APIs and we think this is a step in the right direction.
Here is the wiki if you’re interested in reading about what we have now or contributing to what we might build in the future.
