Wikimedia Bugzilla is closed!

I would like to have a feature that allows me to load diffs but just diffs. <rc> bot reports 
changes on articles on wikipedia, I have a working bot that processes this. I cant load every diff 
on wikipedia edit for practical reasons (bandwidth and cpu). So if I could load just the diffs and 
process that and check for obvious cases of sneaky vandalism. I dont believe it is hard to 
implement this since we already have a function showing the diff (with the rest of the page).
