Hello @tpunt! Although we normally consider this endpoint as public endpoints, commending what @0C3D said, authorization is required or enabled for each endpoint in Advance Trade API to control usage and security of the respective endpoint.
Regarding the migration page to show a mapping of the Coinbase Pro API endpoints, we can consider this as a feedback request for Advance Trade API so we recommend you to share this on the Feedback Section of the forum as most new features and improvements to Coinbase come directly from feedback like yours. Thank you and have a great day!
