Discussion: Determining Auction Sales

Is there any way through the API to capture auction sales?  Would be interesting if there became a Glitch Exchange with indexes, etc.  But need to be able to detect sales to determine market prices.
Hmm, well each auction has a unique ID, and you know the expiry time, so you could just do a differential check. That won't handle the difference between a cancelled one and a sold one though.
I think it would be really useful you could get the the sell information, because then people could get a better understanding of what items are popular and can build accordingly.  The trick I see now, is trying to understand what people are looking for rather than carpet bombing the market looking for success.  You do also see odd things like auctions going for lest the "street" price.
