Playing with API Docs of HTTP.Cat

HTTP.Cat is a fun API website that provides HTTP status codes as cute cat images. Yes, this is a real thing! You can use this API in your projects to add some humor or to make error handling more fun. In this article, we will explore HTTP.Cat API documentation and learn how to make API requests in JavaScript.

API Docs

The HTTP.Cat documentation page is very straightforward. You can find all available HTTP status codes along with their corresponding cat images. The API endpoint is{status_code}.jpg. For example, to get the cat image for the 404 error, you can use the URL

Example Code

To make an API request to HTTP.Cat in JavaScript, you can use the built-in fetch function. Here is an example code snippet that demonstrates how to request the cat image for the 404 status code:

const statusCode = 404;
const url = `${statusCode}.jpg`;

// Request the cat image from the API endpoint
    .then((response) => {
        if (response.ok) {
            // If the response was successful, display the cat image
            const img = document.createElement('img');
            img.src = url;
        } else {
            // If there was an error with the request, log the error message
            console.log(`Error: ${response.statusText}`);
    .catch((error) => {
        console.log(`Error: ${error}`);

This code creates an img element and sets its src attribute to the API endpoint URL. Then it makes a fetch request to that URL and handles the response. If the response is successful, it displays the cat image. If there is an error with the request, it logs the error message to the console.
