🚀 Awesome Dev APIs

A curated collection of awesome free APIs for developers. Open source and community-driven. This repository aims to provide a comprehensive collection of free and freemium APIs to help you build your next project.

GitHub Stars GitHub Forks GitHub Issues GitHub Pull Requests PRs Welcome License: MIT Maintained Visitors Buy Me A Coffee


📚 Code Examples

✨ New! Check out practical code examples showing how to use popular APIs from this collection.
Includes Python & JavaScript examples for Pokemon, Cryptocurrency, AI Chat, and more!


📘 General API Usage Guide

👋 New to APIs? Don't worry! This guide will help you understand the basics and get started quickly.


💡 What is an API?

API stands for Application Programming Interface. It's a way for different applications to communicate with each other.

┌─────────┐      ┌─────────┐      ┌─────────┐
│   YOU   │ ───▶│   API   │ ───▶│ SERVER  │
│  (App)  │ ◀───│ (Waiter)│ ◀───│(Kitchen)│
└─────────┘      └─────────┘      └─────────┘
   Request         Process          Response

Think of it like a restaurant:

  • 🙋 You (the app) place an order
  • 🍽️ Waiter (the API) takes your request to the kitchen
  • 👨‍🍳 Kitchen (the server) prepares your food (data)
  • ✨ The waiter brings it back to you!

📝 Authentication Methods

Different APIs have different ways to verify who you are:

Method Icon Description Example
No Auth 🌐 Open for everyone - just call it! Weather APIs, public data
API Key 🔑 Secret code you get when registering ?api_key=abc123 or Authorization: abc123
OAuth 🔐 Secure login (like "Login with Google") Social media integrations

💡 Pro Tip: Always keep your API keys secret! Never commit them to GitHub.


📡 HTTP Request Methods

Learn the common ways to interact with APIs:

Method Icon Purpose Real-World Example
GET 📥 Retrieve data Get a list of cat pictures
POST 📤 Create new data Upload a new photo
PUT ✏️ Replace existing data Update entire user profile
PATCH 🔧 Modify specific fields Change just your username
DELETE 🗑️ Remove data Delete a comment

Example GET Request:

curl https://api.example.com/cats

Example POST Request:

curl -X POST https://api.example.com/cats \
  -H "Content-Type: application/json" \
  -d '{"name":"Fluffy","age":3}'

🚦 HTTP Status Codes

The API responds with a status code to tell you what happened:

✅ Success Codes (2xx)

Code Icon Meaning
200 OK - Request succeeded!
201 🎉 Created - New resource created!
204 📭 No Content - Success but no data to return

⚠️ Client Error Codes (4xx)

Code Icon Meaning What to Do
400 Bad Request - Invalid syntax Check your request format
401 🔒 Unauthorized - Authentication required Add your API key
403 🚫 Forbidden - You don't have permission Check your access rights
404 🔍 Not Found - Resource doesn't exist Verify the URL
429 🐌 Too Many Requests - Rate limit hit Wait and try again

🔴 Server Error Codes (5xx)

Code Icon Meaning
500 💥 Internal Server Error - API is broken
503 🔧 Service Unavailable - API is down

🛠️ Essential Tools for Testing APIs

Tool Best For Platform Free?
Postman 🎯 Complete API testing & documentation Desktop/Web ✅ Yes (free tier)
Thunder Client ⚡ Lightweight testing in VS Code VS Code Extension ✅ Yes
cURL 💻 Command-line requests Terminal ✅ Yes (built-in)
Insomnia 🎨 Beautiful UI for API testing Desktop ✅ Yes

🚀 Quick Start Example

Let's try a real API call! Here's how to get a random cat fact:

1️⃣ Using cURL (Terminal):

curl https://catfact.ninja/fact

2️⃣ Using JavaScript (Browser):

fetch('https://catfact.ninja/fact')
  .then(response => response.json())
  .then(data => console.log(data.fact));

3️⃣ Using Python:

import requests
response = requests.get('https://catfact.ninja/fact')
print(response.json()['fact'])

📦 Expected Response:

{
  "fact": "Cats have 32 muscles in each ear.",
  "length": 38
}
