What is an API?
A beginner-friendly explanation of APIs and how apps and AI tools connect to each other.
In simple terms
An API is a way for one app or system to talk to another in a structured way.
Think of an API like a waiter in a restaurant.
You tell the waiter what you want, and the waiter brings the request to the kitchen.
Then the kitchen sends the result back through the waiter.
