APIs Explained: How Apps Secretly Talk to Each Other

Your weather app has no weather station inside it. So where does the forecast come from? It asks another computer, through something called an API.
In this video we break down what an API really is: the restaurant waiter analogy, what "Application Programming Interface" actually means, how a request travels from one program to another (endpoints, GET/POST/PUT/DELETE, status codes like 200, 404 and 500), what the answer looks like in JSON, how API keys, rate limits and documentation keep everything running, and why almost every app you use is secretly built from APIs.
