Meetup Alliance is committed to making the data belonging to each Alliance available in a variety of open formats — making it easy to integrate Alliance data anywhere on the web. We currently have a public, read-only API you can work with right away and will be working to open up a read-write API in the coming weeks.
For now we've set up a discussion group to talk about the API and to publish up to date documentation about what's possible — you can join here: alliance-dev.
