Pricing questions

What counts as a request?

A Live call that reaches your workflow counts once, whether it succeeds or fails. REST and MCP calls use the same allowance.

Do Test requests count?

No. Test calls and requests rejected before reaching your workflow are excluded from paid usage.

Is billing per project or per tenant?

Billing is per project. Tenants share the request allowance of the project they access.

What happens when I reach the limit?

Free projects stop at their monthly quota. Pro projects continue only when overages have been enabled.
