Understanding APIs: A Simple Guide
Posted on by admin
APIs let apps talk to each other. Here’s a simple, real example.
Example: Fetching Weather Data
fetch("https://api.openweathermap.org/data/2.5/weather?q=Nairobi&appid=YOUR_KEY")
.then(res => res.json())
.then(data => console.log(data));
Sample JSON Response:
{
"weather": [{ "description": "clear sky" }],
"main": { "temp": 298.15 }
}
This is how front-end apps display weather, maps, payments, etc.
