Any of Quo's 1 trigger in the catalog, including List Phone Numbers. Describe the moment in plain language and your agent picks the right one. ### ### What can your agent do in Retell AI when something happens in Quo? Any of Retell AI's 27 actions, including Create Knowledge Base, Create Retell LLM, Update Agent and Update Call. Your agent maps the data both ways and tests every scenario before it ships. ### ### Can it also run from Retell AI to Quo? Retell AI has no triggers in the catalog today, so automations start in Quo. If you need the other direction, ask: your agent reads Retell AI's API documentation and adds it. ### ### Do I have to build a connector for Quo or Retell AI? 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 Quo and Retell AI 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. Ask for an automation and your agent builds it, tests every scenario and keeps it running. One connection covers both. ### ### What happens when something fails? Your agent works that out for you. It plans the failure paths along with the happy path, then tests every scenario before it ships. ### ### Is there a free plan? Yes. Every plan includes the agent, including free, and building from your own AI client spends no assistant credits.
