This is a great question - there's nothing like discovering an API that opens up new possibilities. I have worked with too many API's to list but one that will always have a special place in my heart is the @Twilio API. It was the first time I used programming to produce an effect I could see in the real world (e.g. write this line of code and you'll receive a phone call). It was also the API I used to create one of my first revenue-generating businesses.
