Reddit Search and Thread Scraper

Search Reddit by keyword, read the newest posts of a subreddit, or read a thread with its comments. You get one flat row per post and, when you ask for them, one row per comment: title, text, author, subreddit, publish date, the post link, the outbound link of a link post, and the search term the post matched. Rows export to CSV or drop into a Clay table, a CRM import, or a monitoring sheet.

Features

• Keyword search, across Reddit or inside subreddits. Each search term runs across all of Reddit, or inside each subreddit you list, sorted by new, relevance, top, most comments, or hot, inside Reddit's own time window.
• Only posts that contain your term. On by default: a result is kept only when your search term is in the post's title or text, so results Reddit returns for other reasons are dropped and not charged. Turn it off to keep every result.
• Subreddit reads. List subreddits with no search term and get their newest, hot, top, or rising posts.
• Threads with comments. Paste thread URLs and get the post plus its top comments, with reply depth you choose. Or turn on Include comments to get the comments of every post a search finds.
• Date limit. Only posts from the last N days, by publish date.
• Only new results. On a schedule, a post or comment an earlier run returned for the same query is skipped and not charged, so each run returns what is new.
• One summary row per query. A free row per search, subreddit, or thread says how many posts Reddit returned, how many were delivered, and how many were skipped and why.
• Cost guards. Max posts per query, max comments per thread, and a max charge per run.

How Reddit is read

The actor reads Reddit's public feeds (RSS), the same pages any feed reader opens, through the Apify proxy. No Reddit account, no login, and no Reddit API key are used, and no other developer's actor is called. The proxy pool rotates the address on every request; a request the pool cannot get through is retried on residential addresses.

Input

Field	Type	Default	What it does
search_terms	array		Keywords to search for. With subreddits, each term runs inside each subreddit
subreddits	array		Subreddits to search in, or to read when there is no search term
thread_urls	array		Thread URLs to read with their comments, up to 200
sort	string	new	Search order: new, relevance, top, comments, hot
subreddit_sort	string	new	Subreddit read order: new, hot, top, rising
time_window	string	month	Reddit's time filter: hour, day, week, month, year, all
since_days	number		Drop posts older than this many days
max_posts_per_query	number	50	Posts per search or subreddit, up to 1,000. Results without your term do not count
require_term_match	true or false	true	Keep a search result only when the term is in its title or text
include_comments	true or false	false	Also return the comments of every post found
max_comments_per_thread	number	25	Comments per thread, top first, up to 500
comment_depth	number	3	Reply levels under each top level comment, 1 to 10
only_new	true or false	false	Skip posts and comments an earlier run returned for the same query (free)
state_key	string		Name for the only new results memory
max_charge_usd	string		Stop before a charge that would pass this amount
proxy_mode	string	auto	auto or residential. A reliability setting; it does not change what you pay

Give at least one of search_terms, subreddits, or thread_urls. Up to 50 searches per run (search terms times subreddits).

comment_id	string	nq2k3ab (comment rows)
title	string	the post title (on a comment row, the title of its post)
body	string	the post or comment text, plain text, up to 20,000 characters
author	string	salesguy42

error_reason	string	why a summary row is not ok
billable_events_json	string	{"post-row":1}, or {} for a free row
scraped_at	string	when the row was written

Reddit's public feeds do not carry upvote scores or comment counts, so the rows do not either. comments_read counts the comment rows this run read for a post.

Pricing

Pay per event. You pay for post rows, comment rows, and the run start. Summary rows, a refused input, search results without your term, and rows already delivered with Only new results on are free.

Event	Free plan	Bronze	Silver	Gold
post-row, one Reddit post	$0.0015	$0.001425	$0.00135	$0.001275
comment-row, one Reddit comment	$0.0015	$0.001425	$0.00135	$0.001275
apify-actor-start, once per run (one per GB of memory; the default 256 MB is one)	$0.003144	$0.003144	$0.003144	$0.003144

Per 1,000 posts: $1.50 on the free plan, $1.28 on Gold.

Free plan cap: 1.50 USD of evaluation a month, about 1000 post or comment rows. Any paid Apify plan removes the cap, and it resets on the 1st. The run stops before a charge that passes your maximum charge per run in Apify or your max_charge_usd.

Mamba Labs pays the platform costs of your run, Apify proxy traffic included.

Usage examples

Apify Console or API.

{
  "search_terms": ["cold email", "lead generation agency"],
  "subreddits": ["sales", "startups"],
  "sort": "new",
  "since_days": 7,
  "max_posts_per_query": 100
}

Read the rows with GET https://api.apify.com/v2/datasets/{datasetId}/items.

A thread with its comments.

{
  "thread_urls": ["https://www.reddit.com/r/sales/comments/1abc23/is_cold_email_dead/"],
  "max_comments_per_thread": 100
}

Clay. Run the actor from a Clay HTTP column or the Apify integration and map the flat columns. Number and on or off inputs are text fields, which is what Clay sends: numbers as text and true or false. A list input takes a JSON list, so put the column inside a one item list.

MCP. The Mamba Labs MCP server @mambalabsdev/mcp-reddit-search-thread-scraper exposes the tool search_reddit to Claude and other MCP clients.

Error handling

Case	What you get
No search term, subreddit, or thread URL, or a value the actor cannot read	One free row, row_type run_summary, error_reason starting input_invalid: with what to fix. The run ends successfully and charges nothing but the run start
A subreddit that does not exist, is private, or is banned	A free summary row, row_status no_results, saying so
A thread that was removed or is in a private subreddit	A free summary row, row_status no_results
Reddit refuses a request	Retried on a new address, then on residential addresses; if every route refuses, a free summary row with row_status blocked
No new posts with Only new results on	A free summary row, row_status no_change
The run is close to its timeout	The actor stops starting new queries 90 seconds before the timeout and delivers what it has

Limitations

• Upvote scores, comment counts, awards, and flair are not in Reddit's public feeds, so the rows do not carry them.
• The actor reads at most 10 pages of 100 results per query. A narrow term with a strict match can return fewer posts than Max posts per query; the summary row says how many results were read and how many were dropped.
• Posts in private subreddits are not in Reddit's public feeds, so they are not returned.
• A deleted author reads [deleted], and a removed post's text is empty.
• Comments come top first. Very long threads return the top comments up to Max comments per thread, not every reply.
