Max Page limitation set to 500
I am currently trying to use your api to gather information about movies to some algorithm. (At this point only to private use).
And I can not gather information beyond page 500. Meaning no more than 10000 movies. This is not ideal for my algorith.
Is it possible to change this to the number of pages you say is accesseble.
In the request you write that there is 41000+ pages available.
Thanks :)

What is possible is to make segmented API Requests.
For example by periods of time or by year.

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

Here's what Travis Bell, the Administrator, said on 2022-06-28:

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.

I believe that only if you make several API Requests.
For example, for decades.

https://api.themoviedb.org/3/discover/movie?api_key=THE_KEY&language=en-US&sort_by=release_date.asc&page=1&primary_release_date.gte=1860-01-01&primary_release_date.lte=1910-12-31  

If I'm not mistaken the movie count must be over 650,000.
EDIT: over 706,322 (2022-06-28)

Depending of the data wanted, the daily export file may be a solution.
