Reddit Comments API. Post comments and replies, page by page.

Post comments and replies, in thread order. We handle the proxies, blocks and platform changes.

Returns the comments on a public Reddit post with their replies, in thread order and a page at a time, from the post's link or ID. Each has its text, author, posting and edit time, score (upvotes), depth and parent, awards, and whether it is by the post's author, pinned, a moderator's, collapsed or deleted. Sort by Reddit's own order, New, Old, Top, Controversial or Q&A. A comment's permalink returns that comment and its replies.

200 OK · GET https://socialtap.dev/v1/reddit/commentsLong arrays and strings are shortened here. Real responses are complete.Docs

One schema on 9 platforms.

The response reference lists every field, its type and when it is null. See the full schema.

Null means unknown
A field Reddit doesn't show is null, never zero or an empty string, so a real zero always means zero.
What it accepts
Reddit post URL: a post's page on any reddit.com host (www, old, new, np, m, sh), with or without its subreddit or slug, a /gallery/ link, a redd.it short link, an app share link (/r/<subreddit>/s/<code>), a v.redd.it video link, or the post's ID (t3_ prefix optional).
Write one parser
Reddit, TikTok, Instagram and 6 more platforms answer in these fields, so the code that reads one reads them all.

platformstring: Platform ID (tiktok, youtube, …).
idstring: Platform-native comment ID (string; Reddit with its t1_ prefix).
post_idstring: ID of the post commented on (equals post.id).
parent_idstring: ID of the comment this replies to; null for top-level comments.
urlstring: Permalink, when the platform has one.
textstring: Comment body as plain text.
authorobject: The commenting account. An account the platform no longer names (a deleted account) has a null id and username and the platform's label as display_name (Reddit: [deleted]).
published_atstring: When the comment was posted, RFC 3339 UTC. Where the platform shows only a relative time ("3 weeks ago"), the latest time that label allows (the fetch time minus the stated amount), listed in approximate_fields.

Good to know before you build.

Comments come in thread order: each one is followed by the replies Reddit shows under it, and parent_id and platform_specific.reddit.depth place it in the thread.
Where Reddit shows a "more replies" link, platform_specific.reddit.more_replies_count says how many replies it holds back. The next pages bring them before the post's next top-level comment, so a walk to the end returns the whole tree.
Walking the whole tree takes several times the requests of replies=shown, because Reddit sends held-back replies a few at a time. replies=shown skips them.
On a thread with hundreds of top-level comments, a walk can leave the most deeply nested held-back replies out once its cursor is full. That page carries an items_omitted warning, more_replies_count still counts them, and that comment's url pages through them.
metrics.like_count is the comment's score (upvotes minus downvotes) when it isn't negative, and platform_specific.reddit.score has it either way. metrics.reply_count is the comment's direct replies when the page shows all of them. It is null when Reddit holds some back behind a "more replies" link, whose count includes their own replies.
Each page continues where the last one ended, so on a busy thread a comment posted during your walk can appear on a later page out of order, never twice.
A deleted account is author {display_name: "[deleted]"} with every other author field null. A deleted or removed comment that has replies stays in the thread with empty text and platform_specific.reddit.is_deleted true.
Posts that don't exist and posts of banned subreddits return not_found. Posts of private or quarantined subreddits return private_or_unavailable. A permalink to a comment that isn't in the post returns not_found.
