10 Fun APIs to Build Your First Project With

February 22, 2026

The best way to learn APIs is to build something with one. But with thousands of APIs out there, it's hard to know where to start. Here are 10 fun, beginner-friendly APIs that are free, well-documented, and perfect for your first project.

1. Dog CEO — Random Dog Images

Auth: None | What it does: Returns random dog photos, filterable by breed.

This is the "Hello World" of APIs. One request, one adorable dog photo. No sign-up needed.

fetch('https://dog.ceo/api/breeds/image/random')
  .then(r => r.json())
  .then(data => console.log(data.message));

Project idea: Build a "random dog" button that shows a new dog photo every time you click it.

2. PokéAPI — Pokémon Data

Auth: None | What it does: Complete Pokémon database with stats, types, abilities, and sprites.

PokéAPI has data for every Pokémon ever created. It's well-structured, fast, and has excellent documentation.

fetch('https://pokeapi.co/api/v2/pokemon/pikachu')
  .then(r => r.json())
  .then(data => console.log(data.name, data.types));

Project idea: Build a Pokédex that lets you search for any Pokémon and see its stats and sprite.

3. Open Trivia Database — Quiz Questions

Auth: None | What it does: Generates trivia questions across dozens of categories and difficulty levels.

fetch('https://opentdb.com/api.php?amount=10&type=multiple')
  .then(r => r.json())
  .then(data => console.log(data.results));

Project idea: Build a trivia quiz app that tracks your score and lets you pick categories.

4. JokeAPI — Programming Jokes

Auth: None | What it does: Returns jokes filtered by category (programming, puns, dark humor, etc.).

fetch('https://v2.jokeapi.dev/joke/Programming')
  .then(r => r.json())
  .then(joke => console.log(joke.setup, joke.delivery));

Project idea: Build a joke-of-the-day widget for your portfolio site.

5. OpenWeatherMap — Weather Data

Auth: API Key (free) | What it does: Current weather, forecasts, and historical data for any location.

One of the most popular free APIs. The free tier allows 1,000 requests per day, which is plenty for personal projects.

Project idea: Build a weather dashboard that shows conditions for your city with icons and a 5-day forecast.

6. The Meal DB — Recipe Search

Auth: None | What it does: Recipe database with ingredients, instructions, and meal photos.

fetch('https://www.themealdb.com/api/json/v1/1/random.php')
  .then(r => r.json())
  .then(data => console.log(data.meals[0].strMeal));

Project idea: Build a "What should I cook?" app that suggests random recipes with ingredients lists.

7. NASA APIs — Space Data

Auth: API Key (free) | What it does: Astronomy Picture of the Day, Mars rover photos, asteroid tracking, and more.

NASA offers some of the coolest free APIs available. The Astronomy Picture of the Day (APOD) endpoint alone is worth exploring.

Project idea: Build a space gallery that shows NASA's Astronomy Picture of the Day with its explanation.

8. Rest Countries — Country Information

Auth: None | What it does: Detailed information about every country — population, languages, currencies, flags, and more.

fetch('https://restcountries.com/v3.1/name/japan')
  .then(r => r.json())
  .then(data => console.log(data[0].capital, data[0].population));

Project idea: Build a country comparison tool that lets you pick two countries and compare their stats side by side.

9. Chuck Norris Jokes — Random Facts

Auth: None | What it does: Random Chuck Norris facts/jokes, filterable by category.

fetch('https://api.chucknorris.io/jokes/random')
  .then(r => r.json())
  .then(data => console.log(data.value));

Project idea: Build a fact generator with a share button that copies the joke to clipboard.

10. JSONPlaceholder — Fake REST API

Auth: None | What it does: Provides fake users, posts, comments, and todos for testing and prototyping.

This isn't a "real" data API — it's a practice API designed for learning. It supports GET, POST, PUT, and DELETE, so you can practice all four CRUD operations.

fetch('https://jsonplaceholder.typicode.com/posts/1')
  .then(r => r.json())
  .then(post => console.log(post.title));

Project idea: Build a mini blog with posts and comments using JSONPlaceholder as your backend.

Tips for your first API project

Start simple. Your first project should be one page with one API call. Add complexity later.
Handle errors. APIs go down. Wrap your fetch calls in try/catch and show a friendly message when things fail.
Read the docs. Every API has quirks. Five minutes reading documentation saves an hour of debugging.
Check the console. When something doesn't work, console.log() the response to see what the API is actually returning.
