Questions
Frihet and Lettermint, answered
What can start an automation from Frihet?
Any of Frihet's 1 trigger in the catalog, including New Expense. Describe the moment in plain language and your agent picks the right one.
What can your agent do in Lettermint when something happens in Frihet?
Any of Lettermint's 8 actions, including Add domain, Add suppression, Get domain and List domains. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from Lettermint to Frihet?
Lettermint has no triggers in the catalog today, so automations start in Frihet. If you need the other direction, ask: your agent reads Lettermint's API documentation and adds it.
Do I have to build a connector for Frihet or Lettermint?
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 Frihet and Lettermint 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.
