Dear All, 

we have put together APIs that make available for each revision: 
Details of the API calls are at http://www.wikitrust.net/vandalism-api
The data should be available for all revisions.  Occasionally, we might lack information for a recent revision. 
Ideally, if a revision is missing, we would put it in a queue of revisions to be processed; I am not sure whether this mechanism is in place already though; but if not, we will provide it soon. 

I hope this is of interest!  We are looking to add more APIs, but this is a start.
