Any of Factur-X by InvoiceXML's 10 actions, including Create Factur-X Invoice, Convert CII XML to Factur-X, Convert Factur-X PDF to CII and Convert Factur-X PDF to UBL. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from Factur-X by InvoiceXML to CallFire?
Factur-X by InvoiceXML has no triggers in the catalog today, so automations start in CallFire. If you need the other direction, ask: your agent reads Factur-X by InvoiceXML's API documentation and adds it.
Do I have to build a connector for CallFire or Factur-X by InvoiceXML?
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 Factur-X by InvoiceXML without building an automation?

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.
