      description: 'This endpoint can be used to validate that a proxy-enabled domain is operational.

        It tries to verify that the proxy URL provided in the parameters maps to a functional proxy that can reach the Clerk Frontend API.


        You can use this endpoint before you set a proxy URL for a domain. This way you can ensure that switching to proxy-based

        configuration will not lead to downtime for your instance.


        The `proxy_url` parameter allows for testing proxy configurations for domains that don''t have a proxy URL yet, or operate on

        a different proxy URL than the one provided. It can also be used to re-validate a domain that is already configured to work with a proxy.'
