http://btc-fork-api.appspot.com/I was looking for this utility, but it didn't seem to exist, so I created it! Essentially you can get an address that whenever funds are sent to it, immediately sends it on to other bitcoin addresses, according to certain settings.
For example, sending bitcoin to Address A might actually have the 20% of the bitcoin end up in Address B, while 20mbtc go to Address C, and the rest go to Address D.
btc-fork-api.appspot.com/new?cases={"addressB":"20%","addressC":"20mbtc","addressD":"default"} will return an address A such that the above example works.
Just a handy API that I will be using even if nobody else does!
