takeScreenshot

GET /v2/takeScreenshot/

Generate a custom screenshot.

You must specify values for either `x1`, `y1`, `x2`, and `y2`
or `x0`, `y0`, `width` and `height`.

By default, the response is a JSON object containing a unique screenshot identifier (`id`) that can be used to with the `downloadScreenshot` API endpoint.

Set the `display` parameter to `true` to directly return the screenshot as binary PNG image data in the response.

Please note that each request causes the server to generate a screenshot from scratch and is resource intensive. For performance reasons, you should cache the response if you simply intend to serve exactly the same screenshot to multiple users.
