Export list functionality and public API functionality (to enable support with apps like Taiga) have been requested for a long time now.
We've heard loud and clear that Taiga support, for example, is important to many when choosing an anime site.
Public API : End of June goal (or sooner if we can swing it). For basic information. Scope: anime database basic info lookup (manga, other types either as a v2 or in the same release). User anime/manga list updating capabilities.
Once the API becomes available, I'll be adding Anime-Planet as a supported service to Taiga.
From the official announcement:
Once the API becomes available, I'll be adding Anime-Planet as a supported service to Taiga.
