Connect CallFire and Castos
When New call fires in CallFire, your agent runs Find Private Subscriber by Email in Castos, or New Episode in Castos to Add contact to list in CallFire. Describe the whole flow and it is built, tested on every scenario and kept running.
What the catalog holds today. Ask for anything missing and your agent reads the API documentation and adds it.
Build solutions, not workarounds.

Questions
CallFire and Castos, answered
What can start an automation from CallFire?
Any of CallFire's 4 triggers in the catalog, including New call, New contact, New SMS text received and New text sent. Describe the moment in plain language and your agent picks the right one.
What can your agent do in Castos when something happens in CallFire?
Any of Castos's 18 actions, including Create Episode, Create Podcast, Create Private Subscriber and Update Episode. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from Castos to CallFire?
Yes. When something happens in Castos, your agent can act in CallFire too. This page covers both directions: Castos's triggers and CallFire's actions are listed here as well.
Do I have to build a connector for CallFire or Castos?
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 CallFire and Castos 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.
