Overview

The Cats API provides access to cat images from Tumblr, with endpoints like /v1/images/search (retrieve filtered cat pictures by breed, size, or type), /v1/breeds (get detailed breed info), and /v1/favourites (manage saved images). Responses are in JSON format. Use cases include adding cat content to apps/websites, educational breed resources, or interactive pet-lover experiences. It supports optional parameters for customization, making it flexible for personal or small-scale projects.
