We have created a new endpoint GET /cards/<id>/cardholder to query information about the cardholder of a given card.
We have also updated the GET /cards (List cards) and GET /cards/<id>(Get card by Id) endpoints. These endpoints now include a new link in the_links section whenever cardholder information is available for a given card.
