Endpoint to access post detail on api.stackexchange site for Android

Question

As it can be seen in the image, which endpoint did it request for class="s-prose js-post-body" class. https://api.stackexchange.com/docs I couldn't see it here, but I need to reach the post details. I would be glad if you help

API = https://api.stackexchange.com/2.3/posts/74254836?order=desc&sort=activity&site=stackoverflow

I can only access these values in post.
