Options Trading Tutorial

What is the best website for downloading stock/forex quotes using an API?

I'm not looking for the traditional stock quotes website where the user types in a symbol and gets a quote. I want a website that offers an API (application programming interface) that a programmer can use to integrate stock/future/option/forex quotes into an application he is building. If it's not a free service then price will be a consideration.
