I wanted to look at a list of items in my Gaia inventory, all using like HTTP wrappers, no gui or anything

Also known as, in a program, being able to click a button and have a list of every item in your inventory pop up.

How would one do this?

(Just the grabbing item names part, not the actual popping up in the program part)

I don't care what language, just give me a general idea of what I need to do, and I can probably do it in whatever language I decide to use.
