Cryptocurrency address generators

[iron888]

I used ShapeShift recently and it seems that they generate new crypto address for each transaction. Looks like they can generate new cryptocurrency address for every coin that is available on their website. There are some APIs to generate BTC, BTH, ETH addresses, but I didn't find an API that could generate new ones for such a big list of cryptocurrencies. Does such an API exist or there is any other way to generate the addresses programmatically?
