Unlike all the other scrapers, this depends on an offline scrape of both MAL and AnimePlanet that maps the entries between them. Entries were mapped by comparing entry titles (or synonyms), as well as entry episode counts and start years. This includes progressively matching from the most exact matches to less certain matches based on fuzzy text matching. Because of this, there may be errors in how entries are mapped - use at your own risk. This mapping is current as of 2022/01/01, but because it is static, it will fail to map newly added entries. If anyone is particularly keen on maintaining this, reach out.

When scraping the list, it scrapes the publicly visible grid view, 560 entries at a time:

https://animeplanet.com/users/user/anime?sort=title&mylist_view=grid&per_page=560

AnimePlanet avoids exposing the database id wherever it possibly can, but the database id does in fact exist, and it so happens that the grid view exposes it. This is crucial, because without this, it becomes infinitely harder to perform the mapping. Counterintuitively, the list view doesn't expose that id. Coincidentally, the 'export' that AnimePlanet offers is also garbage, because it doesn't include the database id. There is also an assumption that that database id is unique to the entry, and that ids aren't reused. Somewhat suspicious given the relatively low maximum database id, so if this assumption is false, the mapping will be broken.

There are mappings for >90% of the current entries, with most of that remainder being music video entries that MAL does not have. There are also a couple of 100 shows that were difficult to match without some serious digging.

There are now mappings for manga, but this is strictly a best-effort match only. There are roughly 3-4x the number of manga to anime, but with much poorer data quality. AnimePlanet disambiguates e.g. Light Novels from Manga in the title as free-form text, making inferring the type difficult. On the other hand, MAL's database is less complete (~40k ~ vs ~60k), with volumes/chapters often not being set.
