We have this data - it’s available in the site setting dropdown. OneBox engines are not allowed to render iframes unless they add the origin to the list first:
They add to the list via the requires_iframe_origins directive:
If the associated origin is not enabled, then the Engine is automatically disabled.
We could do that… but it would mean that new oneboxes will not automatically be added to the list.
Were you thinking of adding all the existing options? Or just a subset of the most common? ![]()
