Meikan is an API with functionality similar to sites like MyAnimeList, AniDB, AniList, Hummingbird, and Anime-Planet.
This API was made because the aforementioned sites have APIs that are lacking in features and are not very open.
Meikan is made by team Fuyu and is currently in development.
Meikan is still under heavy development and there is currently no documentation.
If you wish to use Meikan try contacting team Fuyu.
