  headers: { 'x-api-key': 'YOUR_API_KEY' }
});

const subreddit = await response.json();

Response

{
  "subreddit": {
    "name": "programming",
    "title": "programming",
    "description": "Computer Programming",
    "subscribers": 5800000,
    "activeUsers": 12500
  },
  "posts": [
    {
      "id": "abc123",
      "title": "Why I switched from Python to Rust",
      "author": "rust_evangelist",
      "upvotes": 2500,
      "downvotes": 150,
      "comments": 450,
      "url": "https://www.reddit.com/r/programming/comments/abc123",
      "createdAt": "2026-01-08T10:30:00Z",
      "flair": "Discussion",
      "isStickied": false,
      "awards": 5
    }
  ],
  "hasMore": true
}

Post Comments Scraper

Get all comments from a Reddit post:

const response = await fetch('https://api.sociavault.com/v1/scrape/reddit/post/comments?url=https://www.reddit.com/r/programming/comments/abc123', {
  headers: { 'x-api-key': 'YOUR_API_KEY' }
});

const comments = await response.json();

Response

{
  "comments": [
    {
      "id": "xyz789",

          "upvotes": 45
        }
      ]
    }
  ],
  "totalComments": 450
}

Simple Comments

Get a specific number of comments with a cleaner response:

const response = await fetch('https://api.sociavault.com/v1/scrape/reddit/post/comments?url=https://www.reddit.com/r/programming/comments/abc123&trim=true', {
  headers: { 'x-api-key': 'YOUR_API_KEY' }
});

Search Reddit

Search posts across Reddit:

const response = await fetch('https://api.sociavault.com/v1/scrape/reddit/search?query=best+API+tools+2026', {
  headers: { 'x-api-key': 'YOUR_API_KEY' }
});

const results = await response.json();

Reddit Ads

Reddit ad search and ad details were dropped because Reddit put its Ad Library behind a login wall. For competitor ads, use the Facebook, Google, LinkedIn, or TikTok ad library endpoints instead.

Use Cases

Product Research

Analyze what people say about products:

async function researchProduct(productName) {
  const results = await searchReddit(productName);
  
  // Analyze sentiment
  const posts = results.posts;
  const sentiment = posts.map(p => ({
    title: p.title,
    upvotes: p.upvotes,
    sentiment: analyzeSentiment(p.title)
  }));
  
  return sentiment;
}

Market Research

Find trending topics in a niche:

async function analyzeTrends(subredditName) {
  const { posts } = await getSubreddit(subredditName);
  
  // Find trending topics
  const topics = {};
  posts.forEach(post => {
    const words = post.title.toLowerCase().split(/\s+/);
    words.forEach(w => {
      if (w.length > 4) topics[w] = (topics[w] || 0) + post.upvotes;
    });
  });
  
  return Object.entries(topics)
    .sort((a, b) => b[1] - a[1])
    .slice(0, 20);
}

Competitor Analysis

Track mentions of competitors:

async function trackCompetitors(competitors) {
  const mentions = {};
  
  for (const competitor of competitors) {
    const results = await searchReddit(competitor);
    mentions[competitor] = {
      totalPosts: results.posts.length,
      totalUpvotes: results.posts.reduce((s, p) => s + p.upvotes, 0),
      sentiment: results.posts.filter(p => p.upvotes > 0).length / results.posts.length
    };
  }
  
  return mentions;
}

Customer Feedback Mining

Extract feedback from relevant subreddits:

async function mineFeedback(subreddits, keywords) {
  const feedback = [];
  
  for (const sub of subreddits) {
    const { posts } = await getSubreddit(sub);
    
    const relevant = posts.filter(p =>
      keywords.some(k => p.title.toLowerCase().includes(k))
    );
    
    for (const post of relevant) {
      const { comments } = await getPostComments(post.url);
      feedback.push({
        post: post.title,
        comments: comments.slice(0, 10)
      });
    }
  }
  
  return feedback;
}

Ad Research

This use case relied on the Reddit ads endpoints, which were dropped (see Reddit Ads above). For competitor advertising, use the Facebook, Google, LinkedIn, or TikTok ad library endpoints.

Frequently Asked Questions

Can I scrape private subreddits?

No, only public subreddits are accessible. Private communities require membership.

How far back can I get posts?

You can access historical posts through pagination, though Reddit's search has limitations on very old content.

Are NSFW subreddits supported?

The API focuses on SFW content. NSFW subreddits may have limited access.

Can I get user post history?

Currently, the API focuses on subreddit and post-based scraping. User profiles aren't directly supported.

How does this compare to Reddit's official API?

SociaVault provides similar data access without Reddit's strict rate limits and API key requirements.
