Questions
Stax and Fly.io Machines API, answered
What can start an automation from Stax?
Any of Stax's 1 trigger in the catalog, including List Payment. Describe the moment in plain language and your agent picks the right one.
What can your agent do in Fly.io Machines API when something happens in Stax?
Any of Fly.io Machines API's 11 actions, including Create App, Create Machine, Create Volume and Update Machine. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from Fly.io Machines API to Stax?
Fly.io Machines API has no triggers in the catalog today, so automations start in Stax. If you need the other direction, ask: your agent reads Fly.io Machines API's API documentation and adds it.
Do I have to build a connector for Stax or Fly.io Machines 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 Stax and Fly.io Machines 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.
