Headless Browser API — Full Browser Power via REST

Run headless Chrome in the cloud via a simple REST API. Capture screenshots, generate PDFs, extract structured data, and analyze pages — all without managing Puppeteer, Chrome binaries, or containerized browser infrastructure.

Code Examples

Node.js

// Headless browser screenshot in 3 lines
const res = await fetch(
  "https://api.snapapi.tech/v1/screenshot?" +
  new URLSearchParams({ url: "https://example.com", full_page: "true" }),
  { headers: { "X-API-Key": "YOUR_KEY" } }
);
// Returns raw PNG bytes — same as Puppeteer page.screenshot()
const png = Buffer.from(await res.arrayBuffer());

// Structured page analysis (replaces Puppeteer page.evaluate)
const analysis = await fetch(
  "https://api.snapapi.tech/v1/analyze?url=https://example.com",
  { headers: { "X-API-Key": "YOUR_KEY" } }
).then(r => r.json());
// Returns: title, headings, links, text_content, technologies, load_time_ms

Why SnapAPI?

No Browser Setup

We run Chromium so you don't have to. No Puppeteer, no Selenium, no drivers.

PNG, JPEG, WebP

Choose your format. Set quality. Get optimized output.

Mobile Emulation

9 device presets � iPhone, Pixel, iPad, desktop. One parameter.

Full Page Capture

Scroll the entire page and stitch into one image. Automatic.

Element Selector

Capture a specific element by CSS selector instead of the whole page.

Dark Mode

Emulate prefers-color-scheme: dark to capture dark-themed pages.

How It Works

1. Sign up for a free API key � 100 screenshots/month, no credit card required.

2. Make a GET request to /v1/screenshot with your URL and API key.

3. Receive a pixel-perfect screenshot as a binary image, or JSON with metadata if meta=true.

That's it. No browser installation, no Chromium management, no headless infrastructure to maintain.
