🔒 Billing and Limits
Billing
Sentio measures usage in Sentio Units (SU) and issues bills at the end of each month. The USD price per SU depends on your plan.
Billing Rules
- All processor usage is billed to the project owner.
- All API usage is billed to the API caller (identified by API key).
Free Usage
The following incur no charges:
- Usage from the Sentio UI.
- Usage from the processor in backfill stage
If a bill remains unpaid for one month, the service will be automatically suspended.
