Quickstart

Take your first screenshot in under two minutes.

1. Get an API key

Sign up at api.nightglass.xyz/dashboard and grab your API key from the dashboard. You get 50 free screenshots to start.

2. Take a screenshot

curl

curl -X POST https://api.nightglass.xyz/api/v1/screenshot \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -d '{"url": "https://example.com"}' \
  --output screenshot.png

That's it. The response is a PNG image. Save it, display it, pipe it — it's just bytes.

3. Try mockup mode

Want the screenshot wrapped in a browser frame? Add "style": "mockup":

curl

curl -X POST https://api.nightglass.xyz/api/v1/screenshot \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -d '{"url": "https://example.com", "style": "mockup"}' \
  --output mockup.png

For AI agents: You don't need an API key at all. Just call the endpoint without an auth header — you'll get a 402 response with x402 payment details. Pay with USDC on Base, and you get your screenshot. See agent payments.
