The first release of the Ohloh API is now available. You can read the documentation and sign up on the API page.
We’re releasing early to get as much feedback as possible. This is a very early beta with limited functionality.
The API is a work in progress, and we will be actively expanding the API every day. If there’s a particular dataset you’d like to access, let us know, because new API methods will be implemented based on demand.
We’re very excited about this, and hope to see some very interesting applications!
