Ember - using api/server data

I am new to ember and I like what I see so far. I have done the tutorial and found to to be pretty easy to get something up and running. My question has to do with using mirage vs real data. I used mirage to stub in some data but now I would like to link to to real data. I would think this should not be too hard since I have the models..etc set up I just need to call an api instead of mirage. I have not seen a clean example of how best to do this.

Thanks
