  description: 'The Polylang language configuration for www.exentis-group.com — the site is published
    in German (de_CH, default) and English (en_US), and this endpoint is what tells a client which locales
    exist, which is default, their home and search URLs and their content counts. Every other collection
    on this host accepts the resulting `lang` slug as a filter.


    Derived by API Evangelist from the live WordPress REST API discovery document at https://www.exentis-group.com/wp-json/
    and an anonymous sample response.'
