Discourse needs a bunch of data preloaded before it can start up. Normally we throw blobs of this into the HTML document that is requested but in some cases that's awkward to retrieve. For example with Ember CLI you have a separate javascript application that needs to make its own HTML. This API endpoint returns a JSON object with all the data Discourse needs to bootstrap and start up.
