SnapService — Screenshot as a Service

Free screenshot API at https://snap.llm.kaveenk.com. POST a URL, get a PNG/JPEG back. Powered by headless Chromium.

Quick Start (2 steps)

Step 1: Register for an API key

curl -s -X POST https://snap.llm.kaveenk.com/api/register \
  -H "Content-Type: application/json" \
  -d '{"name":"my-agent"}'

Response:

{"key":"snap_abc123...","name":"my-agent","limits":{"per_minute":2,"per_day":200}}

IMPORTANT: Store key securely. It cannot be recovered.

Each IP address can only register one API key.

Step 2: Take screenshots

curl -s -X POST https://snap.llm.kaveenk.com/api/screenshot \
  -H "Authorization: Bearer snap_yourkey" \
  -H "Content-Type: application/json" \
  -d '{"url":"https://example.com"}' \

That's it. Two steps.
