Discover --> Collections API endpoint
Hello,
it would be great to have Discover --> Collection endpoint available in the API. Now I need to

1. find movies with Discover --> Movie,
   
2. then find only movies which belong to some collection
   
3. and get collection details for every found collection id.
   

3 API calls instead of 1 may be 2.
Or at least, would be possible to add new boolean filter "movie_belongs_to_collection" in Discover --> Movie endpoint?

Maybe this will make your job easier.
The list of all valid IDs of all TMDb items. Collection.
https://developer.themoviedb.org/docs/daily-id-exports
In your case, all valid Collection IDs.
http://files.tmdb.org/p/exports/collection_ids_02_16_2025.json.gz
Pay close attention to the date format. MM_DD_YYYY.

Data Example:

{"id":10,"name":"Star Wars Collection"}
{"id":84,"name":"Indiana Jones Collection"}
{"id":119,"name":"The Lord of the Rings Collection"}
{"id":131,"name":"Trois Couleurs Collection"}
{"id":151,"name":"Star Trek: The Original Series Collection"}
{"id":230,"name":"The Godfather Collection"}
{"id":263,"name":"The Dark Knight Collection"}
{"id":264,"name":"Back to the Future Collection"}
{"id":295,"name":"Pirates of the Caribbean Collection"}
{"id":304,"name":"Ocean's Collection"}
{"id":328,"name":"Jurassic Park Collection"}

I need to use Discover endpoint due to availability of filters, sorting options...to be able to create collection catalogs like Popular, New releases, Top rated

It is definitely feasible with ids export + daily collection/movie details calls + sorting.., but it overloads both servers and it isn't that efficient as calling discover endpoint.
