Free Web Metadata Extractor API - Get Title, Description, OpenGraph Data

Extracting metadata from websites is tedious. You need to fetch HTML, parse the DOM, extract og:title, og:image, description meta tags, handle encoding issues, and normalize results. Libraries like BeautifulSoup require setup and run slowly. What if you could extract metadata via REST API and get structured JSON instantly?

The Web Metadata Extractor API fetches any URL and returns all metadata: page title, description, OpenGraph tags (image, video, type), Twitter Card tags, favicon, structured data (JSON-LD), and more. Perfect for link preview, SEO analysis, social media automation, and content aggregation.

Why Use This API?

Parsing HTML locally means:

• Network overhead (fetching the page)
• DOM parsing complexity
• Encoding issues (UTF-8, charset detection)
• Slow execution on large pages

This API: instant results, consistent parsing, all metadata in one call, zero setup.

Quick Example - cURL

# Extract metadata from a URL
curl "https://meta-extractor-api.p.rapidapi.com/extract?url=https://example.com" \
  -H "X-RapidAPI-Key: YOUR_KEY" \
  -H "X-RapidAPI-Host: meta-extractor-api.p.rapidapi.com"

Response:

{
  "success": true,
  "url": "https://example.com",
  "title": "Example Domain",
  "description": "This domain is for use in examples and documentation.",
  "favicon": "https://example.com/favicon.ico",
  "images": ["https://example.com/image.jpg"],
  "opengraph": {
    "title": "Example Domain",
    "description": "An example domain",
    "image": "https://example.com/og-image.jpg",
    "type": "website",
    "url": "https://example.com"
  },
  "twitter_card": {
    "card": "summary",
    "title": "Example Domain",
    "description": "An example domain",
    "image": "https://example.com/twitter-image.jpg"
  },
  "structured_data": {
    "@type": "WebPage",
    "name": "Example Domain",
    "description": "An example domain"
  }
}

Python Example

import requests
import json

url = "https://meta-extractor-api.p.rapidapi.com/extract"
headers = {
    "X-RapidAPI-Key": "YOUR_API_KEY",
    "X-RapidAPI-Host": "meta-extractor-api.p.rapidapi.com"
}

# Extract metadata from multiple URLs
urls = [
    "https://www.wikipedia.org",
    "https://github.com/torvalds/linux",
    "https://news.ycombinator.com"
]

for target_url in urls:
    params = {"url": target_url}
    response = requests.get(url, params=params, headers=headers)
    data = response.json()

    if data["success"]:
        print(f"\n{data['title']}")
        print(f"  {data['description']}")
        if data.get('opengraph', {}).get('image'):
            print(f"  Preview: {data['opengraph']['image']}")
    else:
        print(f"Error: {data.get('error')}")

JavaScript / Node.js Example

const axios = require("axios");

const extractMetadata = async (targetUrl) => {
  const response = await axios.get(
    "https://meta-extractor-api.p.rapidapi.com/extract",
    {
      params: { url: targetUrl },
      headers: {
        "X-RapidAPI-Key": process.env.RAPIDAPI_KEY,
        "X-RapidAPI-Host": "meta-extractor-api.p.rapidapi.com"
      }
    }
  );

  const data = response.data;
  return {
    title: data.title,
    description: data.description,
    image: data.opengraph?.image || data.twitter_card?.image,
    favicon: data.favicon
  };
};

// Build a link preview widget
const urls = [
  "https://dev.to/miccho27",
  "https://github.com/tmizuno27"
];

Promise.all(urls.map(extractMetadata)).then(previews => {
  previews.forEach(p => console.log(`${p.title} - ${p.description}`));
});
