I am trying to create an app that uses my feed data, I want to have all the posts (not only mine but of the followers too) that appear in my feed in the official app but after reading the documentation I am confused about whether it is possible to do so or not. Also, can I do keyword searching through API in data to obtain all the posts related to that keyword?

I have read the documentation and gotten to know a few endpoints but they will all return only the post that I have created or shared not the entire feed data.
