No, you cannot get all of them in one call. Yes, when you send a request to one of the /search endpoints, the output includes how many pages are there in total.

thank you!
i have another question,
is there a way to get all of the movies available in a service in one call?
if not, is there a way to see how many pages there are for each service?

Hey, if you mean to get IMDb Top 250 Movies (https://www.imdb.com/chart/top/) , there’s no direct support for that. You need to get IMDb ids of those some other way, then you can query one of the /get endpoints to get streaming availability of each one.

If you mean just getting the top rated movies of a specific service, you can use /search/ultra endpoint and order the results by imdb_rating. i.e. if you do that for Netflix US, you can get the all movies there ordered by their IMDb ratings.
