# Nekosia API

**Canonical:** https://apis.io/providers/nekosia/  
**Website:** https://nekosia.cat/  
**APIs profiled:** 1

Nekosia is a free, keyless anime-image REST API serving cute anime "neko" (catgirl) imagery and related metadata, backed by the provider's own Booru. Three documented GET operations return JSON carrying dominant colours, original and compressed image variants, dimensions, tags, content ratings, anime and character names, the original source and full artist attribution. No API key, no registration and no account are required; rate limits are enforced per IP address and reported through standards-track RateLimit response headers. Standard public use is free, but commercial use requires prior written consent from the operator.
