Frequently Asked Questions
What viewports are available?
Desktop (1280x720), Tablet (768x1024), Mobile (375x812), and 1080p (1920x1080). The API also supports a 4K preset (3840x2160).
Is this tool free?
Yes, completely free with no signup. For programmatic access, create a free API key (200 credits). Each screenshot costs 1 credit.
What browser is used for rendering?
Screenshots are rendered using Chromium via Puppeteer, so you get the same rendering quality as Chrome/Edge. JavaScript is fully executed before capture.
Can I capture full-page screenshots?
The default capture is viewport-sized. Full-page screenshots that scroll the entire page are available via the API by setting "fullPage": true in your request.
How do I use the API programmatically?
Send a POST request to https://agent-gateway-kappa.vercel.app/v1/agent-screenshot/api/screenshot with a JSON body containing url and optionally viewport. The response is a PNG image. Use /api/screenshot/json for base64 JSON output with metadata.
Are there rate limits?
Free usage is generous (200 credits). Each screenshot costs 1 credit. For higher volume, top up with USDC or Monero at our pricing page.
