How to Build a Trending Topics Dashboard with One API Call — Google, Reddit, HN, GitHub, Product Hunt

#webdev #api #javascript #python

Every content creator, marketer, and indie hacker needs to know what's trending right now. But scraping Google Trends, Reddit, Hacker News, GitHub, and Product Hunt individually? That's 5 different APIs, 5 auth flows, and a maintenance nightmare.

I built a single API that aggregates trending topics from all five sources in one call. It runs on Cloudflare Workers (300+ edge locations, sub-50ms latency) and costs $0 to try.

What You Get

One GET /trends request returns:

  • Google Trends — top daily & real-time searches
  • Reddit — r/all hot posts
  • Hacker News — front page stories with scores
  • GitHub — trending repos (daily/weekly)
  • Product Hunt — daily top products

Each item includes: title, URL, source, score/votes, and timestamp.

Quick Start

Python — Get All Trending Topics 

import requests

url = "https://trends-api.p.rapidapi.com/trends"
headers = {
    "X-RapidAPI-Key": "YOUR_KEY",
    "X-RapidAPI-Host": "trends-api.p.rapidapi.com"
}

response = requests.get(url, headers=headers)
data = response.json()

for source, items in data["trends"].items():
    print(f"\n--- {source.upper()} ---")
    for item in items[:3]:
        print(f"  {item['title']} ({item.get('score', 'N/A')} pts)")
Enter fullscreen mode Exit fullscreen mode

JavaScript — Filter by Source 

const response = await fetch(
  "https://trends-api.p.rapidapi.com/trends?source=github",
  {
    headers: {
      "X-RapidAPI-Key": "YOUR_KEY",
      "X-RapidAPI-Host": "trends-api.p.rapidapi.com"
    }
  }
);
const { trends } = await response.json();
console.log("Trending GitHub repos:", trends.github);
Enter fullscreen mode Exit fullscreen mode

Real-World Use Cases

  1. Content Calendar Generator — Fetch trending topics weekly, auto-generate blog post ideas based on overlap between Google Trends and Reddit
  2. Slack Bot — Post a daily digest of what's hot in your niche to #general
  3. Competitor Monitoring — Track when competitors appear on Product Hunt or HN
  4. SEO Content Brief — Cross-reference Google Trends with HN/Reddit to find topics with both search demand and community interest
