I built a Screenshot & Metadata API that extracts 50+ fields from any URL

Source: Dev.to

What it does

• URL to Screenshot – capture any webpage as PNG, JPEG, or WebP
• URL to PDF – generate PDFs with custom format, margins, orientation
• Metadata Extraction – 50+ fields from any URL (see below)
• HTML to Image – render custom HTML/CSS to PNG/JPEG/WebP

The Metadata Endpoint

A single GET request extracts:

Basic SEO

• title, description, keywords, author, language, charset, viewport, robots, canonical URL, generator

Open Graph

• og:title, og:description, og:image (+ dimensions), og:url, og:type, og:site_name, og:locale

Twitter Card

• card type, title, description, image, @site, @creator

Icons & Theme

• favicon, apple-touch-icon, manifest, theme-color, color-scheme

Content Analysis

• first h1 text, h2 count, internal links count, external links count, images count, images without alt text, forms count, scripts count, stylesheets count, word count

Structured Data

• JSON‑LD (Schema.org) parsed and returned

Feeds

• RSS/Atom feeds auto‑detected

Raw dump

• All meta tags as key‑value pairs

Quick Start (Python)

import requests

headers = {
    "X-RapidAPI-Key": "YOUR_KEY",
    "X-RapidAPI-Host": "screenshot-pdf-api.p.rapidapi.com"
}

# Screenshot a website
response = requests.get(
    "https://screenshot-pdf-api.p.rapidapi.com/v1/screenshot",
    headers=headers,
    params={"url": "https://github.com", "width": 1280, "format": "png"}
)

with open("screenshot.png", "wb") as f:
    f.write(response.content)

print(f"Saved {len(response.content)} bytes")

Quick Start (JavaScript)

// Screenshot
const response = await fetch(
  "https://screenshot-pdf-api.p.rapidapi.com/v1/screenshot?url=https://github.com&format=png",
  {
    headers: {
      "X-RapidAPI-Key": "YOUR_KEY",
      "X-RapidAPI-Host": "screenshot-pdf-api.p.rapidapi.com"
    }
  }
);
const blob = await response.blob();

// Metadata
const meta = await fetch(
  "https://screenshot-pdf-api.p.rapidapi.com/v1/metadata?url=https://github.com",
  {
    headers: {
      "X-RapidAPI-Key": "YOUR_KEY",
      "X-RapidAPI-Host": "screenshot-pdf-api.p.rapidapi.com"
    }
  }
);
const data = await meta.json();
console.log(data.data.title);      // "GitHub · Build and ship software..."
console.log(data.data.og_image);   // "https://..."
console.log(data.data.word_count); // 834
