What counts as an event?
For usage, we count tasks: one accepted event received by Axel, and one initial event pushed to a destination. Rejected requests do not count.
Are retries billed?
No. Retries are included. If your destination fails and Axel retries delivery, those retry attempts do not create more billable tasks.
Why count received and pushed events?
Received events pay for durable ingest and replay. Pushed events pay for fan-out work. Counting both keeps single-destination usage cheap while making multi-destination fan-out predictable.
What happens after the $20 credit?
Usage continues at $0.03 per 1,000 tasks. The dashboard shows received events, pushed events, task usage, and the estimated invoice before the month closes.
