Questions
Circleback and OpenHolidays API, answered
What can start an automation from Circleback?
Any of Circleback's 2 triggers in the catalog, including New Action Item and New Meeting. Describe the moment in plain language and your agent picks the right one.
What can your agent do in OpenHolidays API when something happens in Circleback?
Any of OpenHolidays API's 7 actions, including Find Public Holidays by Date, Find School Holidays by Date, List Countries and List Languages. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from OpenHolidays API to Circleback?
OpenHolidays API has no triggers in the catalog today, so automations start in Circleback. If you need the other direction, ask: your agent reads OpenHolidays API's API documentation and adds it.
Do I have to build a connector for Circleback or OpenHolidays API?
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 Circleback and OpenHolidays API 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.
