Overview

Cataas (Cat as a Service) provides RESTful endpoints for accessing a vast library of cat images and GIFs. Users can fetch random cats, filter by tags (e.g., 'sleep', 'play'), or retrieve specific content. Responses are image files (JPG/PNG) or GIFs; append ?json=true for metadata in JSON format. It supports customizations like resizing, rotating, or overlaying text. Ideal for integrating cat content into apps, websites, chatbots, or testing media handling features without hosting assets.

Example Integration (JavaScript)

script.js JS

fetch('https://cataas.com/')
  .then(res => res.json())
  .then(data => console.log(data))
  .catch(err => console.error(err));
