Bit.ly URL Shortener for Yahoo Pipes

I need a sub-yahoo pipe that will take a URL of a feed, replace each ITEM's URL and generate a [login to view URL] URL that is coded to my [login to view URL] username/api key. The [login to view URL] URL needs to be output in the item's link or a created [login to view URL] link field. I want to use this sub-pipe to add the [login to view URL] url to the end of an item title. (ie. [login to view URL] [login to view URL]) - and anticipate putting this sub-pipe at the top of my pipe, so that after I manipulate the title per my specifications I can add a string builder at the end affixing the [login to view URL] URL to the end of the title.
