Getting started

Parameter	Required	Default	Description
subreddit	Yes	—	Subreddit name (e.g. technology, worldnews, r/science)
sort	No	hot	Feed sort order: hot / new / top / rising / best
timeFilter	No	day	Time range for top sort only: hour / day / week / month / year / all
maxResults	No	100	Number of posts to collect (10–500)
includeComments	No	false	Collect comments for each post
maxCommentsPerPost	No	10	Max comments per post, top-level and replies combined (1–100). Only applies when includeComments is true
maxReplyExpansions	No	1	How many times to expand hidden replies per thread. Set to 0 to skip, higher values load deeper reply chains. Only applies when includeComments is true
enableAI	No	false	Enrich each post with AI-generated bodySummary and commentSummary fields.

Example — posts only:

{
  "subreddit": "Entrepreneur",
  "sort": "hot",
  "maxResults": 100
}

Example — posts with comments:

{
  "subreddit": "Entrepreneur",
  "sort": "hot",
  "maxResults": 50,
  "includeComments": true,
  "maxCommentsPerPost": 10
}

Example — posts with AI analysis:

{
  "subreddit": "Entrepreneur",
  "sort": "hot",
  "maxResults": 50,
  "includeComments": true,
  "maxCommentsPerPost": 10,
  "enableAI": true
}

Click Start in the Apify console or call it via API. Results are available as JSON, CSV, or Excel.

AI Analysis output

When enableAI is true, each post in the dataset is enriched with:

• bodySummary — a concise summary of the post's body text (text posts only)
• commentSummary — a summary of the comment discussion, covering what people agree on, push back on, and additionally suggest

Both fields are only present when the relevant content exists (body or comments). Posts with no body and no comments will not have either field.

Pricing estimate

Event	Unit	Price
Post	per post	$0.00199
Comment	per comment (includeComments: true)	$0.00099
AI body summary	per post with body (enableAI: true)	$0.001
AI comment summary	per post with comments (enableAI: true)	$0.002

Note: AI summaries are charged per post, not per comment. A post with 100 comments still generates one commentSummary — billed once at $0.002.

Scenario	Posts	Comments	Estimated cost
Posts only	1,000	—	~$1.99
Posts + 10 comments each	1,000	10,000	~$11.89
Posts + 50 comments each	500	25,000	~$25.70
Posts + AI body summary only	1,000	—	~$2.99
Posts + comments + AI (body + comment summary)	500	5,000	~$7.44

Comment collection is billed per comment. AI summaries are billed per post. Keep maxCommentsPerPost low if you only need a sample of opinions per post.

What can you do with it?

Sentiment analysis and brand monitoring Pull the latest posts from a niche subreddit with sort: new and enable comments to capture raw, unfiltered opinions. Reddit comments are more candid than reviews or tweets — people say what they actually think.

Build AI training datasets Subreddits like r/AskReddit, r/explainlikeimfive, or r/relationship_advice contain millions of long-form human discussions. Enable includeComments with maxCommentsPerPost: 50 to capture full conversation threads — ideal for fine-tuning, RLHF, or building Q&A datasets.

Track community trends over time Run weekly on r/investing or r/technology with sort: top and timeFilter: week to see which topics are gaining traction. Combine post scores, comment counts, and upvote ratios to spot momentum early.

Research what content resonates Compare score, upvoteRatio, and commentCount across hundreds of posts to understand what titles and formats drive engagement. Use comment depth and score to see which perspectives the community amplifies.

For developers

JavaScript / TypeScript

import { ApifyClient } from 'apify-client';

const client = new ApifyClient({ token: 'YOUR_API_TOKEN' });

const run = await client.actor('YOUR_ACTOR_ID').call({
  subreddit: 'technology',
  sort: 'top',
  timeFilter: 'week',
  maxResults: 100,
  includeComments: true,
  maxCommentsPerPost: 10,
});

const { items } = await client.dataset(run.defaultDatasetId).listItems();
console.log(items);

Python

from apify_client import ApifyClient

client = ApifyClient('YOUR_API_TOKEN')

run = client.actor('YOUR_ACTOR_ID').call(run_input={
    'subreddit': 'technology',
    'sort': 'top',
    'timeFilter': 'week',
    'maxResults': 100,
    'includeComments': True,
    'maxCommentsPerPost': 10,
})

for item in client.dataset(run['defaultDatasetId']).iterate_items():
    print(item)

Limitations

• Volume: 10 to 500 posts per run.
• Post body text: Only available on text posts. Link, image, video, and gallery posts return null for body.
• Comment body: Text comments return the full comment text. Image-only or GIF comments (no text) return the media URL as body instead of null.
• Images: Only available on image and gallery posts — null for all other types. image posts return a permanent i.redd.it URL. gallery posts return signed preview.redd.it URLs that expire approximately 7 days after scraping.
• timeFilter: Only applies when sort is set to top. Ignored for all other sort orders.
• Comments: Up to 100 comments per post (maxCommentsPerPost). This count includes both top-level comments and replies. Reddit initially hides some replies behind "load more" buttons — use maxReplyExpansions to control how many times those are expanded per thread (default: 1). Set to 0 to collect only what's visible on initial load.
