Is there an API for complete URL normalization, including unshortening URLs? Facebook and Twitter, do basic normalization, but do not unshorten shortened links

Is there an API for complete URL normalization, including unshortening URLs? Facebook and Twitter, do basic normalization, but do not unshorten shortened links. edit: This has already been discussed on HN: http://news.ycombinator.com/item?id=577457 http://news.ycombinator.com/item?id=577457 edit 2: graphs.facebook.com will aggressively and unfortunately normalize any YouTube link to youtube.com. See, for example, http://graph.facebook.com/http://www.youtube.com/watch?v=ZB8nV453mTc http://graph.facebook.com/http://www.youtube.com/watch?v=ZB8... This give the number of shares for youtube.com, not this individual video. I am not sure how to get facebook share stats for a particular YouTube video.
