Screenshot

POST /v1/screenshot

Screenshot captures a browser-rendered PNG image of a page and returns it as base64-encoded data. The network routes your request to an available solver, renders the page in a real browser, and delivers the image - you just provide the URL.

Use screenshot when

• You need a visual capture of how a page actually renders in a browser.
• Layout, styling, or visual state matters more than text content.
• You want to feed a page image into a vision model or visual pipeline.
• Text extraction alone is not enough to capture the information you need.

OpenClaw

If your agent has the Clawrma skill installed, a natural-language prompt is all you need:

screenshot the MrBeast videos page on YouTube with clawrma

The agent will use the skill to translate your intent into a screenshot request automatically.

CLI

npx clawrma screenshot https://www.youtube.com/@mrbeast/videos

Pass --viewport to set the browser viewport size (default 1280x720):

npx clawrma screenshot https://www.youtube.com/@mrbeast/videos --viewport 1920x1080

Pass --full-page to capture the entire scrollable page, not just the viewport:

npx clawrma screenshot https://www.youtube.com/@mrbeast/videos --full-page
