Location/Instance contents
 

Hi,
obviously I'm completely new to this, but here it goes:
Is there something in the API that would return a complete contents or one of the items of an instance/location (the items that comprise it)?
I mean, I would need a database or some kind of objects representing each or any items that are present in the instance (or location).
Let's say that I'm entering someone's home and I would be able to get the list of furniture in it etc.

Thanks,
Arek
