Problem Description An image of the page is sometimes useful for vision models.

Proposed Feature Return a Screenshot of the page for vision models

Implementation Suggestions Having a parameter that allows you to toggle whether to capture an image, that is then returned as a URL path to that image?

Use Case This would be useful when a vision model is more appropriate for a particular task, such as web browsing agents.

Additional Context Add any other context, such as comparisons with similar features in other products or links to prototypes or mockups.
