API and Collections [Risolto]

I'm getting ready to build an application to help me view and manage my collection and items in my collection, but reading the documentation I'm not sure that this is supported.  I need to be able to retrieve a list of my collections, then for each one that I retrieve (one, all, or some) all of the coins in that collection.  Is this a supported option?

Actually looks as if I need the /user endpoints but just use my user ID, if anyone else has tried something else which works better then that would be great to hear about.

I’ve written some php code to do this. I have more types than the 2000 monthly api call limit so it takes more than a month to pull all the types, but then you can generate any list you like. I keep an offline html copy of my collection on a tablet  that I take with me to shows with collapsing country sections so I can quickly see if I already have a type I’m about to buy.
