Mashery recently open-sourced a new interactive API documentation system called Mashery I/O Docs. It’s available from Github.
I/O Docs enables developers to experiment with API calls from within the documentation. You can see it in action at Posterous and Wordnik Alibris and Klout (correction: the Posterous and Wordnik APIs were the inspiration for I/O Docs, but don’t use I/O Docs).
