Known For Movies & Acting Section
Dear,
I was wondering how I can get the known for movies of an actor/actress in their personal details page
(example : https://www.themoviedb.org/person/1253360-pedro-pascal )

First, I think this is worth reading.
https://www.themoviedb.org/bible/people#5a0b12e49251416561000001

As far as I looked into the API, I didn't find a way to get them I only could get all the movies.

Second, I think it will be better to use a Discover API Request.
https://developers.themoviedb.org/3/discover/movie-discover
That's because you can filter by movie popularity or by highest vote.
I think it's not exactly the Know_For order but it should be very close.
Example:

https://api.themoviedb.org/3/discover/movie?api_key=THE_KEY&language=pt-BR&sort_by=popularity.desc&page=1&with_cast=1253360
https://api.themoviedb.org/3/discover/movie?api_key=THE_KEY&language=pt-BR&sort_by=vote_average.desc&page=1&with_cast=1253360

Also, for the acting session at the same page, where can I get those details from?

In the example above I asked only with_cast.
Could order with_crew.
Or order with_people, Cast and Crew.
Some details of each movie are in the answer.
More details only by making API Request of the basic or complete data of each movie, using the ID.

if there is no API request for them, any ideas or ways to get them or filter them?

I don't know any other way.

Thanks for the response! Found it. Problem Solved.
