Overview
Danbooru is a large anime image board with a structured tagging system covering thousands of anime artists and characters. Beginners can use it to explore anime artwork and search images by character, series, or artist tags. Its API lets you query image metadata, tags, and artist records programmatically.
Beginner Tip
You need a free account and API key for most endpoints; anonymous requests are rate-limited to 2 requests/second. Start with GET /posts.json?tags=<character_name> to search by character.
