Rate limit: 60 requests per 60 seconds. This is the default shared quota — it is shared with every other endpoint that has no dedicated limit, so requests across those endpoints all draw from the same budget.

Creates a reply nested under an existing comment. Replies are 1-level deep — replying to a reply attaches to the same parent comment with an inline @mention to the reply author. Increments parent comment’s repliesCount and the post’s totalCommentsAndReplies.
