URLBox - BoostGPT Documentation

Rendered screenshots and PDFs of a URL. The same job as ScreenshotOne, a different renderer.

Connecting

In the dashboard, open Connectors, find URLBox and press Connect. The key you enter is checked against URLBox before anything is saved, so a key that is refused never becomes a connection that fails later.

What you will need

Field	What it is
API Key	Your URLBox API Key from the dashboard

Getting the credential

Go to URLBox and sign up
Copy your API Key from the dashboard Settings
Paste it into this connector

Notes

render_sync is best for images (PNG/JPEG/WebP/SVG)
render_async is best for video (MP4/WebM) and large PDFs
Renders are cached by default — use force: true to bypass
ttl controls cache duration in seconds

See URLBox API docs for the full reference.
