Is it possible to fetch watch providers for a large number of movies without having to make an API call for each individual movie?

I'd like to have a browse screen when the user can view potentially hundreds of movies categorised by the watch providers they are available on. i.e There'd be an 'Available on Netflix' section, and 'Available on Hulu' section....

Stuff i've considered: I understand you can get this information by querying each movie individually. However i don't want to burden the API with thousands of individual API calls. I also understand i can specify specific watch providers via the 'discover' endpoint. However this doesn't meet my use-case because i need to specify the movies that are queried (not be provided random ones).

Is there any mechanism (current or planned) whereby i could get watch providers for hundreds of movie ID's in a single query that wouldn't get my API key blocked for being a rascal?
