Questions
Castos and AddressZen, answered
What can start an automation from Castos?
Any of Castos's 3 triggers in the catalog, including New Episode, New Podcast and New Private Subscriber. Describe the moment in plain language and your agent picks the right one.
What can your agent do in AddressZen when something happens in Castos?
Any of AddressZen's 9 actions, including Find addresses by search term, Find places by search term, Freeform US Address Verification and Get address. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from AddressZen to Castos?
AddressZen has no triggers in the catalog today, so automations start in Castos. If you need the other direction, ask: your agent reads AddressZen's API documentation and adds it.
Do I have to build a connector for Castos or AddressZen?
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 Castos and AddressZen 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.
