What can your agent do in fastbill when something happens in Quilia?
Any of fastbill's 18 actions, including Create Customer, Create Invoice, Create Offer and Create Revenue. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from fastbill to Quilia?
fastbill has no triggers in the catalog today, so automations start in Quilia. If you need the other direction, ask: your agent reads fastbill's API documentation and adds it.
Do I have to build a connector for Quilia or fastbill?
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 Quilia and fastbill 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.
