🚀 How to Use

Getting started with any API in this list is simple! Here's a quick walkthrough:

Step 1 — Pick an API

Browse the categories above and find an API that matches your project's needs. Look at the Auth column to find the easiest one to start with — 🟢 No Auth APIs work right in your browser!

Step 2 — Get Access (if required)

For 🟡 API Key APIs:

1. Visit the API's documentation link
2. Sign up for a free account
3. Copy your API key from the dashboard

Step 3 — Make Your First Request

Example: Fetch a random dog image (No Auth needed)

curl https://dog.ceo/api/breeds/image/random

Example: Get weather data with Open-Meteo (No Auth)

curl "https://api.open-meteo.com/v1/forecast?latitude=52.52&longitude=13.41&current=temperature_2m"

Example: Get country info with REST Countries (No Auth)

curl "https://restcountries.com/v3.1/name/india"

Example: Using an API key (e.g., OpenWeatherMap)

curl "https://api.openweathermap.org/data/2.5/weather?q=London&appid=YOUR_API_KEY"

Step 4 — Parse the Response

Most APIs return JSON. Here's how to handle it in common languages:

// JavaScript (fetch API)
const res = await fetch('https://dog.ceo/api/breeds/image/random');
const data = await res.json();
console.log(data.message); // URL to dog image

# Python (requests library)
import requests
response = requests.get('https://dog.ceo/api/breeds/image/random')
data = response.json()
print(data['message'])  # URL to dog image

# Bash + jq (pretty print JSON)
curl -s "https://restcountries.com/v3.1/name/france" | jq '.[0].capital'

📌 Pro Tip: Use tools like Postman, HTTPie, or Insomnia to explore APIs visually before writing code!
