How to Capture Website Screenshots with an API

Taking automated screenshots of websites is a common requirement for developers building monitoring tools, generating reports, or creating visual archives. In this guide, we'll show you how to capture pixel-perfect screenshots using the WebTools API.

Why Use a Screenshot API?

Running your own headless browser (Puppeteer, Playwright, Selenium) is:

• Resource-intensive — Chromium uses 200–500MB of RAM per instance
• Complex to maintain — Browser updates, font rendering, dependency management
• Hard to scale — Concurrent requests can crash your server

A screenshot API handles all of this for you. One HTTP request → one screenshot.

Getting Started

First, sign up for a free API key. You get 100 free requests per month — no credit card required.

Basic Usage

cURL

curl "https://tools.f5rvoice.com/api/v1/screenshot?url=https://github.com&apikey=YOUR_KEY" -o screenshot.png

Python

import requests

response = requests.get("https://tools.f5rvoice.com/api/v1/screenshot", params={
    "url": "https://github.com",
    "apikey": "YOUR_KEY"
})

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

print(f"Screenshot saved! Status: {response.status_code}")

Node.js

const fs = require('fs');

const response = await fetch(
  `https://tools.f5rvoice.com/api/v1/screenshot?url=https://github.com&apikey=YOUR_KEY`
);

const buffer = await response.arrayBuffer();
fs.writeFileSync('screenshot.png', Buffer.from(buffer));

Advanced Options

Full-Page Screenshot with Custom Size

curl "https://tools.f5rvoice.com/api/v1/screenshot?url=https://news.ycombinator.com&width=1920&height=1080&fullPage=true&apikey=YOUR_KEY" -o full.png

Common Use Cases

1. Visual regression testing — Compare screenshots before and after deployments
2. Social media previews — Generate OG image thumbnails dynamically
3. Client reports — Include website screenshots in PDF reports
4. Web archiving — Capture periodic snapshots of competitor websites
5. Content moderation — Screenshot user-submitted links for review
