Hi @elmanci2, you probably need to be more specific about your questions. No one can design a program for you without knowing all your requirements.

Here is a general outline

Get the items from the list: https://developer.themoviedb.org/reference/list-details

The results contain the genre ids, so group by genre id(s) (in code).

Get recommendations for whatever movies in your list you want (or all of them). This would have to be called for each movie: https://developer.themoviedb.org/reference/movie-recommendations
