Build a Reddit Content Feed With One API Call

If you've ever tried scraping Reddit for post data, you know the pain — rate limits, authentication tokens, parsing nested JSON trees. The Reddit Subreddit Posts API cuts through all of that. One GET request, any subreddit, structured data back instantly.

What It Does

This API returns top and trending posts from any public subreddit. Pass in a subreddit name and get back post titles, scores, comment counts, authors, URLs, and more — all in clean JSON. No OAuth setup, no Reddit app credentials, no dealing with Reddit's API versioning headaches.

It's useful for:

Content dashboards that aggregate trending topics across communities
Market research tools that track brand mentions or competitor discussions
Notification bots that alert when a topic gains traction in a relevant subreddit
Data analysis projects that need structured Reddit data without the scraping overhead

Quick Start

Here's how to pull the latest posts from any subreddit using fetch():

const subreddit = 'webdev';

const response = await fetch(
  `https://social-media-api-production-b82a.up.railway.app/api/posts?subreddit=${subreddit}`
);

const data = await response.json();

data.posts.forEach(post => {
  console.log(`${post.title} (score: ${post.score})`);
  console.log(`  by u/${post.author} | ${post.commentCount} comments`);
  console.log(`  ${post.url}`);
  console.log();
});

Swap 'webdev' for any subreddit — javascript, machinelearning, startups, reactjs — and you get the same structured response.

Why Use an API Instead of Scraping?

Reddit's official API requires OAuth tokens, has strict rate limits (100 requests per minute for authenticated users), and returns deeply nested response structures. Scraping the HTML is fragile and breaks whenever Reddit ships a frontend update.

This API handles all of that behind the scenes. You get a stable endpoint, consistent response format, and no authentication ceremony.

Real Use Case: Trend Tracker

Imagine building a dashboard that monitors r/programming, r/javascript, and r/devops simultaneously. With three fetch calls you'd have a live pulse on what the developer community is talking about — then sort by score to surface what's actually resonating.
