Work you can account for.

Each verified account receives 100 free credits per UTC calendar day. The allowance resets at midnight UTC and does not accumulate.

One credit covers up to 10 seconds of execution, rounded up per task. Queue time is free. Before a task starts, its maximum runtime is reserved from your balance. Unused credits return when it ends.

Daily free credits are used first, then subscription credits, then purchased packs. A refund to an expired daily or subscription allowance does not extend its expiry.

Cancelled or unsuccessful tasks are charged only for recorded work. Failures before work starts and worker restarts are refunded. If a worker response is lost, the reservation stays held until the task can be reconciled safely.
