As the World Wide Web continues to grow and permeate our everyday lives, an ever-increasing amount of data and digital services are accessible to us through public web APIs - Application Programming Interfaces. Common to many web sites, including YouTube, Twitter, Google Maps, Wikipedia and more, web APIs offer a means to programmatically request and re-purpose endless troves of information. But how exactly do we access these datasets and services? How can we write code to transfer, store, and display this content on our own web sites? And how might we use these available resources to design unique, creative, and compelling web experiences of our own.
