What this API does

The Cataas API (Cat as a Service) provides a rich collection of random cat images, GIFs, and memes. It is designed for developers looking to add engaging feline content to their applications. This RESTful API allows for retrieving cat images with optional text overlays and tag filtering, ensuring a high degree of customization. The API returns JSON metadata for each image, making it easy to integrate and manipulate the data in various applications.

How it works

Developers can make HTTP GET requests to various endpoints to retrieve different cat images. You can fetch a random cat image, add custom captions, or filter images by specific tags. Each response includes metadata in JSON format, giving you all the necessary information about the image, such as URL and dimensions. The example endpoints include retrieving random images and images with specific tags.
