How an agent gets them
They appear on the same connection address the moment a Zinn® Chat Pro licence is active on the site: no new application password and no change in your AI app. On a site without the licence they are not offered to the agent at all, so it never tries one it cannot use. Each still checks the WordPress permission it names.
