Can I trigger a browser task with a different starting URL?

Yes! Use the `run_task` tool and provide the Task ID. In the `overrides` field, you can pass a JSON object like `{"url": "https://newsite.com"}` to change the starting point dynamically.

How do I see the screenshot captured by a task?

Simply ask the agent to `get_run` and provide the Run ID. Once the status is 'finished', the response will include a `screenshot_url` that you can click to view the image.

Does the integration allow taking a quick screenshot without a saved task?

Yes. Use the `take_screenshot` action and provide the URL. It will create a simplified run that captures the page and returns the result URL once processed.
