We're delighted to say that we've just released a very basic start point for the oodlu.org API. We will be building on this over coming weeks to enhance it. Currently it just has two basic endpoints. One for checking the credentials and the other for getting a list of questions for a question collection.
Watch this space!
Here is a quick video overview of how the API works.
We hope this is fun and look forward to hearing what you create with it!
