Request limits
I have a question,
if we call API (for example: /movie/popular), then as a result we will get 20 popular movie data.
Well, what if I call the same API, but I only want to get data from 10 popular movies.
Are there any additional parameters when I call the API?

The number/quantity of Items per Page and the number/quantity of Pages
cannot be changed, configured, specified, restricted, or anything like that.
There will always be up to 20 items per page.
And a maximum of 500 pages.
Therefore, at most 10,000 items.

Of course, depending on the parameters used in your API Request
this number/quantity can be much smaller.
Eventually zero.

In a Trending API Request, the quantities are greater.
A maximum of 1,000 pages
Therefore a maximum of 20,000 items

Unfortunately, there is no planned change on the page limit.
We still show the total results so one can get an accurate count but that is all.
