How to GET JSON data from API using Python

This article will guide you on how to use Python to send a GET request to an API and receive JSON data. You will learn how to work with necessary libraries and handle the data.

In this article, we will use Python's requests library to send a GET request to an API and receive JSON data. The sample code will help you understand how to do this easily and effectively.

import requests

# API endpoint
url = "https://api.example.com/data"

# Send GET request
response = requests.get(url)

# Check status code
if response.status_code == 200:
    # Convert JSON data
    data = response.json()
    print(data)
else:
    print(f"Request failed with status code: {response.status_code}")

Detailed explanation

1. import requests: Imports the requests library to use its HTTP request functionalities.
2. url = "https://api.example.com/data": Defines the API endpoint you want to send a request to.
3. response = requests.get(url): Sends a GET request to the specified URL and stores the response in the response variable.
4. if response.status_code == 200:: Checks if the response status code is 200 (success).
5. data = response.json(): If the request is successful, converts the received JSON data into a Python object.
6. print(data): Prints the data to the console.
7. else:: If the request is not successful, prints the response status code.

System Requirements

• Python version 3.x
• requests library (can be easily installed)

How to install the libraries needed to run the Python code above

You can install the requests library using pip:

pip install requests

Tips

• Always check the response status code before processing the data.
• Read the API documentation to understand how to use it and the required parameters.
