Screenshot API for Developers

Everything a screenshot API should do

One endpoint, every option you'll actually need.

Simple REST API. Works from anywhere.

One HTTP request. No SDKs required (though we have those too).

curl

# Basic screenshot — returns PNG binary
curl "https://snapapi.tech/v1/screenshot?url=https://github.com" \
  -H "x-api-key: YOUR_KEY" \
  -o screenshot.png

# Full-page, dark mode, iPhone 14 emulation
curl "https://snapapi.tech/v1/screenshot?url=https://github.com&full_page=true&dark_mode=true&device=iphone14" \
  -H "x-api-key: YOUR_KEY" \
  -o iphone-dark.png

# URL to PDF
curl "https://snapapi.tech/v1/pdf?url=https://github.com&format=A4" \
  -H "x-api-key: YOUR_KEY" \
  -o page.pdf

Node.js

const fs = require('fs');

async function screenshot(url, output) {
  const res = await fetch(
    `https://snapapi.tech/v1/screenshot?url=${encodeURIComponent(url)}&full_page=true`,
    { headers: { 'x-api-key': process.env.SNAPAPI_KEY } }
  );
  if (!res.ok) throw new Error(await res.text());
  fs.writeFileSync(output, Buffer.from(await res.arrayBuffer()));
  console.log(`Saved: ${output}`);
}

screenshot('https://github.com', 'github.png');

// Batch — screenshot multiple URLs in parallel
const res = await fetch('https://snapapi.tech/v1/batch', {
  method: 'POST',
  headers: { 'x-api-key': process.env.SNAPAPI_KEY, 'Content-Type': 'application/json' },
  body: JSON.stringify({ urls: ['https://stripe.com', 'https://vercel.com'], endpoint: 'screenshot' })
});
const { results } = await res.json();
// results[i].screenshot = "data:image/png;base64,..."
