Post Reddit comment

Post a top-level comment on a Reddit post by its URL. Returns the created comment's id, permalink, author, created timestamp and score. Posts a real comment under the logged-in account; this is a top-level comment on the post, not a reply to another comment. Runs only via the browser extension, not the hosted cloud browser.

Input

url required

Post URL — full https://www.reddit.com/r/.../comments/... or just the /r/.../comments/... path

text required

Comment body (plain text / markdown). Supports inline @-mentions (u/name) and links, which Reddit auto-links.

Output

author required
commentId required

Fullname of the created comment, e.g. t1_xxxxx

permalink required
account_used required

The real logged-in Reddit handle that performed the action, read from the page's own account drawer (not assumed from args)

already_present required

Whether an identical top-level comment by this account already existed on this post before posting (checked against the post's own comment list)

verified_on_page required

Whether the script reloaded the post afterward and confirmed the new comment is actually visible there

score optional
created optional

Get Reddit thread

Fetch a full Reddit thread from its URL. Returns title, op_text, score, num_comments, and comments (author, body, score, nesting depth). Compare num_comments to total_comments to detect truncation; use all_comments to expand every "more replies" thread automatically.

Search Reddit

Search posts across all of Reddit (no subreddit restriction), with optional sort and time window. Returns count and threads (each with id, url, title, author, subreddit, score, num_comments, created, nsfw, preview_text). `limit` is a maximum: fewer matching posts than requested returns however many exist. Useful to discover which subreddits discuss a topic. Reddit refuses connections from datacenter addresses, so this works as-is on your own browser; on a hosted cloud browser the session has to be given a country so it exits through a residential address, otherwise Reddit blocks it and the script says so.

Get subreddit threads

List a subreddit's threads by Reddit's native sort (best/hot/new/top/rising). "new" is chronological (filter with `since`); "top" takes a `time` window (hour…all); others paginate by `limit`. Returns url, title, author, score, num_comments, created, post_type, and body — the post's full text (never truncated; null for link/image posts). `limit` is a maximum, not a guarantee: fewer matching threads returns what exists.
