What is an API? (in 3 minutes)

Three and a half minutes, one analogy, and "we'll expose it through an API" finally makes sense. The video casts an API as a waiter in a restaurant: you never deal with the back of house yourself, you hand your order to someone who carries it there and brings back what you asked for. It was made by MuleSoft, a company that sells API software, so expect a little of its own world. The waiter picture is the part worth keeping, and it holds up well when engineers start talking about requests, responses and connecting one product to another.
