}Get mentions of the account
The posts that @-mention the selected account right now, newest first
(or ranked by engagement with sort=top), each with the post it
replies to and one further level of ancestry.
This reads X live rather than SuperX’s stored posts, and one call walks several upstream pages plus the parent posts, so it charges a flat 3 units of the plan’s feed bucket. Read a page and work from it rather than polling.
By default, mentions the account has already replied to on X are left
out. include_replied=true keeps them and sets replied on each one.
mention_type separates a direct reply to one of the account’s posts
(reply) from any other @-mention (mention).
Paging is by cursor: pass pagination.next_cursor back as cursor.
The app’s Mentions tab also hides posts you skipped or blocked there. That list is a UI preference stored with the app, so it is not applied here: the API returns every mention and lets you filter your own way.
