I am trying to get a count of unanswered questions by tag. Basically if there was an 'unanswered-count' in addition to the 'count' property of the /tags response that would be perfect.
It has been suggested that I use /questions/unanswered with the tag filter. However I would have to query the API thousands of times every time I wanted to update the unanswered count. I just want the list of tags like it is on the right side of SO when you click on 'Unanswered'.
What I want to do is every five or 10 minutes get the top 10 tags by unanswered questions count, but to get the top 10 I have to know the count of all the others (so I know which ones are the top 10). Perhaps there is an algorithm that does not require one to go through the entire list of items to determine the top 10?
