Armory is a project mainly written in Python, it's free.
Python module for accessing the World of Warcraft armory
This python module includes some simple ways to fetch data from the WoW armory. I wrote it back in late 2008, and haven't really touched it since, but it still works.
It's incomplete. Patches are welcome. I may fix it up myself if I ever remember what I was originally writing it for.
The main finished part of armory is armory.get_character. Like so:
import armory retcon = get_character('us', 'Lothar', 'Retcon') retcon.name u'Retcon' retcon.items[0] <armory.EquippedItem object at 0x865e8ac> retcon.items[0].id 47674 retcon.items[0].name u'Helm of Thunderous Rampage'
