First API request and response in Rest API - Mini Project: Build & Apply

First API request and response

📖 Scenario: You are building a simple program to get the current weather from a public API. This will help you learn how to make your first API request and see the response.

🎯 Goal: Learn how to send a GET request to a weather API and display the temperature from the response.

📋 What You'll Learn

Use the requests library to make an API call

Send a GET request to the URL https://api.weatherapi.com/v1/current.json?key=demo&q=London

Extract the temperature in Celsius from the JSON response

Print the temperature with a friendly message

💡 Why This Matters

🌍 Real World

APIs let programs get live data from websites and services. Weather apps use APIs to show current weather.

💼 Career

Knowing how to make API requests is a key skill for developers working with web services, mobile apps, or data integration.

1

Set up the API URL

Create a variable called url and set it to the string 'https://api.weatherapi.com/v1/current.json?key=demo&q=London'.

Rest API

# Create the API URL
# Your code here

Need a hint?

Use a string variable to store the full API URL exactly as given.

2

Import requests and make the GET request

Import the requests library and create a variable called response that stores the result of requests.get(url).

Rest API

url = 'https://api.weatherapi.com/v1/current.json?key=demo&q=London'
# Import requests and get the response
# Your code here

Need a hint?

Use import requests at the top. Then call requests.get(url) and save it in response.

3

Extract temperature from JSON response

Create a variable called data that stores the JSON content from response using response.json(). Then create a variable called temp_c that gets the temperature in Celsius from data['current']['temp_c'].

Rest API

import requests

url = 'https://api.weatherapi.com/v1/current.json?key=demo&q=London'
response = requests.get(url)
# Extract JSON data and temperature
# Your code here

Need a hint?

Use response.json() to get the data. Then access the temperature with data['current']['temp_c'].

4

Print the temperature

Write a print statement that outputs: "The current temperature in London is {temp_c}°C." using an f-string.

Rest API

import requests

url = 'https://api.weatherapi.com/v1/current.json?key=demo&q=London'
response = requests.get(url)
data = response.json()
temp_c = data['current']['temp_c']
# Print the temperature with a message
# Your code here

Need a hint?

Use print(f"The current temperature in London is {temp_c}°C.") to show the temperature.
