Balance, reserved, and available
A reservation covers worst-case authorized exposure. It is not the final charge. Confirmed usage settles against its reservation. Uncertain authorized usage can remain reserved while reconciliation completes.
Deleting a machine does not turn a missing usage report into zero usage. Check the reconciled balance after cleanup.
Funded deadlines
Temporary machines have a funded deadline. Adding credit alone does not extend that deadline: extend the machine timeout before it ends if you need more runtime. Temporary machines delete when their lifetime ends. Persistent machines use rolling funded windows. When another window cannot be funded, the machine pauses. Retained memory and disk enter a configurable credit grace period, which defaults to 14 days. Adding credit can make it resumable again. Read the machine’s returned grace deadline.Key budgets
A key may also have a lifetime spending ceiling. Both the organization balance and the key budget must cover commitments. Available organization credit does not override an exhausted key budget. See API key budgets.Add funds
Add credit through a persisted purchase, or configure automatic refill with admin authority. Trial credit spends before paid deposits because it expires. Runbead pricing or call GET /v1/pricing for current rates. See workload estimates before provisioning.
