Imagine you’re in a restaurant.
You sit at a table and look at the menu. You don’t go into the kitchen to cook your food yourself. Instead, a waiter comes, takes your order, and brings the food back to you.
That waiter is basically an API.
You (the app) don’t talk directly to the kitchen (server or database). You send a request through the API, and it brings back what you asked for.
For example:
- You open a weather app
- The app asks an API: “What’s the weather in Paris?”
- The API goes to the server, gets the data, and returns it
- You see the result on your screen
So the API is just a middle layer that lets different systems talk to each other safely and in a structured way.
Without APIs, apps would have to directly access databases or systems, which would be messy, unsafe, and hard to manage.
With APIs, everything stays organized:
- apps ask for data
- APIs handle the request
- servers send the response
That’s it - just like ordering food without walking into the kitchen.
