# Lemmy Post Comments API

A post's comments as a normal page, with path, depth and parent id so you can walk any branch.

`GET /v1/lemmy/post/comments?instance=lemmy.world&postId=53910627&sort=Top` returns `data.comments`, each with `id`, `content`, `postId`, `path`, `depth`, `parentId`, `distinguished`, `languageId`, `removed`, `deleted`, `publishedAt`, `score`, `upvotes`, `downvotes`, `replyCount`, `post`, `community` and `author`. Give `postId`, `parentId`, or both; `parentId` lists that comment and its replies.

Large reply trees are not returned whole. Use `path` to see ancestry, `depth` for the level and `parentId` to walk one branch at a time. A postId or parentId that does not exist returns not_found; a real post with no comments returns a found answer with no rows.

## FAQ

### How do I get replies to one comment?

Pass parentId with the comment id. The answer includes that comment and its replies; add postId to keep the request anchored to its post.

### Why is the whole tree not in one response?

A full tree can be hundreds of kilobytes. This route returns a normal page; path, depth and parentId let you walk the branches you need.

### Why is a comment's content empty?

A moderator can remove a comment or its author can delete it, and the instance then serves an empty content with removed or deleted set. The moderation log may still hold the removed text.

### How many credits does a comment page cost?

Pricing is documented on the operation in the API registry (shown on this page). Confirm on every response with meta.creditsCharged: that field is the billing source of truth. Each paginated page is a separate billed request.
