Get Screenshot

Serve the page screenshot, optionally resized to w pixels wide. Public endpoint.

Omitting w always returns the capture as stored, which for a page scan is the full scrollable page (bounded crawler-side), not just the viewport. Passing w returns a thumbnail whose height is capped at 2.5x its width, so an over-tall page is cropped to its top region — fetch without w when you need the whole page.
