Page capture: screenshot or PDF of a public URL

$0.01 USDC per call · Developer and security · POST /api/v1/page-capture · Id page-capture

Renders one public web page in a real browser (Cloudflare Browser Run, JavaScript enabled) and returns a PNG or JPEG screenshot or a PDF as base64 with its sha256, for agents that need to see or archive a page. Does not log in, click or fill forms, does not capture private or internal hosts, and returns an error rather than a capture larger than 6 MB.

What you get

A rendered screenshot or PDF of any public page without running a headless browser.
