Reflection/introspection on an Ember application to find instances of a specific model

First of all, I'm not looking to learn everything about Ember. I only want to use it on an existing Ember application to extract information about the application state.

I'm developing a Chrome extension to let users download "raw" Vine videos from the Vine website. Vine is basically an Ember application and you can easily use the Ember Inspector to introspect the application and extract the video URLs manually.

So what I'm thinking is I'll do something akin to whatever they're doing.

Where do I start looking?
