HTTP Cat

About HTTP Cat

HTTP Cat is a service that returns an image of a cat corresponding to a given HTTP status code, accessed by appending the status code to the base URL (https://http.cat/[status_code]), with an optional .jpg extension. It covers a wide range of status codes across informational, success, redirection, client error, and server error categories, including standard codes like 200, 404, and 500 as well as less common ones such as 418, 451, and 508.

The images were originally created by Tomomi Imura, and the site is developed by Rogério Vicente. It is aimed at developers who want a visual, illustrative way to represent HTTP status codes, such as in documentation, error pages, or testing tools.
