Sub-pages with breadcrumb

To retrieve a specific page whose URL you’ve gotten from one of the previous responses (in the links/self attribute of the item) with its ancestor pages for the breadcrumb and its shared content elements (add ?include=ancestors,contents to the page URL):

http://mydomain.tld/api/cms/pages/2?include=ancestors,contents

The included section contains the list of shared content elements that should be displayed at the page if include=contents is added as parameter to the JSON:API URL the anchestor pages if the include parameter also contains ancestors, e.g.:

{

        "baseurl": "http:\/\/mydomain.tld\/storage\/"
