I looked for a solutin like more than hour, but not chance. There is a function to reset cache of a specific page manually? I'm using wp super cache.

I'm updating some posts meta values using API, and I want when I update something, I reset the cache of this page only. There is a function for that?

The function you're looking for is wpsc_delete_post_cache()

$post_id = 123;
  • if I can ask, what is the difference with wp_cache_post_change() function?

    While not formally declared as such in the codebase, wp_cache_post_change() is more like an event handler. It responds to post edits. And while it does much the same thing as wpsc_delete_post_cache(), there are several runtime considerations made by that function, making it slightly less desirable if you're intention is explicitly to clear a specific post ID. Calling wp_cache_post_change() may or may not result in the cache being cleared, or it may result in multiple areas of the cache being cleared. It considers constants, actions, and customizable filters.

  • Note that wpsc_delete_post_cache() also deletes the post author's posts page.

    ok, I didn't understand the last phrase : "deletes the post author's posts page.". what do you mean with posts pages? it delete cache of all posts of that author?
