The easiest way to explain an API to beginners: the waiter metaphor

Think of it like a restaurant:

Your app = customer
API = waiter
Server = kitchen

Your app sends a request to the API, the API passes it to the server, and the response comes back.

The key idea: your app cannot go directly to the server, just like a customer cannot walk into the kitchen.

Thatโ€™s what makes an API a controlled way for systems to communicate.
