No. Both are in the catalog with their triggers and actions. You describe the automation; your agent builds it, tests every scenario and keeps it running. ### ### Can my AI client use FreeAgent and Stax without building an automation? Yes. With your AI client connected to APIANT, ask it to do something in either app once and it runs that action on the spot.
