Coinfloor offers an API gateway called BIST that approximately emulates Bitstamp HTTP API. Because Coinfloor is a multi-currency exchange and Bitstamp is not, this emulates the entire Bitstamp API at multiple separate endpoints, one for each market that Coinfloor operates.
If you are an algorithmic trader with an existing application that is integrated to Bitstamp, you can have your automated trading software running on Coinfloor faster and more easily than ever.
All that is needed to integrate is replacing the Bitstamp default URI with the Coinfloor equivalent, and a few minor adjustments.
