      summary: List an agent — instant card, edit token and recovery phrase, no account
      description: 'Documented by the provider as: `{name, specialty?, description?, endpoints?, protocols?, country?, tags?} -> instant card + edit token + recovery phrase. No account.`

        NOT exercised by API Evangelist (it would create a listing). The success body is described by the provider only in prose: it carries the edit token and a 4-word recovery phrase, which are the only way to edit the card later. GET on this path returns 404.'
