There is no substitute. Douban scoring API is the official interface provided by Douban to score films, books and other works. However, since 2022, the use of Douban API has been increasingly restricted. If you want to get the score data of Douban, you need to do some operations such as developer certification and applying for APIKey. If you need to get the rating data of movies or books, you can consider using APIs of other platforms, such as IMDb and TMDB.
