Interactive API explorers in Rest API - Mini Project: Build & Apply

Interactive API Explorer

📖 Scenario: You want to explore a public API to see what data it returns. This helps you understand how to use the API in your projects.Imagine you are curious about a simple API that gives you information about users.

🎯 Goal: Build a simple interactive API explorer that fetches user data from a public API and shows the results.

📋 What You'll Learn

Create a variable with the API URL

Create a variable to hold the user ID to fetch

Write code to fetch data from the API using the user ID

Print the fetched user data

💡 Why This Matters

🌍 Real World

APIs are everywhere. Being able to explore and understand them helps you build apps that use data from other services.

💼 Career

Many jobs require working with APIs to get or send data. Knowing how to fetch and read API responses is a key skill.

1

Set up the API URL

Create a variable called api_url and set it to the string "https://jsonplaceholder.typicode.com/users/".

Rest API

api_url = "https://jsonplaceholder.typicode.com/users/"
# Your code here

Need a hint?

This URL is the base for fetching user data by ID.

2

Set the user ID to fetch

Create a variable called user_id and set it to the number 3.

Rest API

api_url = "https://jsonplaceholder.typicode.com/users/"
user_id = 3
# Your code here

Need a hint?

This ID will be used to get data for user number 3.

3

Fetch user data from the API

Write code to fetch data from the API by combining api_url and user_id. Use the requests library to get the data and store the JSON response in a variable called user_data. Use requests.get(f"{api_url}{user_id}") and then call .json() on the response.

Rest API

import requests

api_url = "https://jsonplaceholder.typicode.com/users/"
user_id = 3

# Your code here

Need a hint?

Use requests.get with an f-string to combine the URL and user ID. Then call .json() on the response.

4

Print the fetched user data

Write a print statement to display the user_data variable.

Rest API

import requests

api_url = "https://jsonplaceholder.typicode.com/users/"
user_id = 3

response = requests.get(f"{api_url}{user_id}")
user_data = response.json()

# Your code here

Need a hint?

Use print(user_data) to show the fetched information.
