Overage

Eligible paid accounts are billed $0.01 per credit after spendable balances are exhausted.

The server allows overage only when all of the following are true:

1. The profile is on a paid plan.
2. The Stripe subscription status is active.
3. Overage is enabled for the subscription.
4. The operation successfully settles with charge_source: "overage".

The ledger ID identifies the usage receipt. Failed operations and idempotent replays do not create another overage charge.

Eligibility

Overage is never a request toggle. Free accounts, inactive subscriptions and paid accounts without overage eligibility stop with 402 after other balances are exhausted.

The operation response identifies the balance source that was used. When overage is active, a successful request returns charge_source: "overage" and the number of credits charged. A response with an unknown balance does not imply that overage is available; retry after the account state has loaded or contact support before continuing automated traffic.

Request behavior

Overage follows the same operation and idempotency contract as prepaid or included credits:

• Send one idempotency key for one logical operation.
• Reuse that key when retrying an uncertain response.
• Do not generate a new key merely because the client timed out.
• Treat 402 as a balance or eligibility decision, not as a transient scoring failure.

An idempotent replay returns the existing operation receipt and does not create a second charge. If a replay reports that processing is still in progress, wait before checking the same operation again.

Failure boundaries

An inVerus failure reverses the reservation and produces no overage charge. If a successful Console receipt and later invoice disagree, do not rerun the assessment; contact support with the ledger ID.

Review usage

Open Usage & Billing to review operation name, timestamp, charged credits and charge source. Overage activity is separate from included, prepaid and gifted balances so the source of each successful debit remains visible.

Before increasing automated traffic, confirm that the Console shows an active paid subscription and a known balance state. If the plan, cycle date or available balance is unavailable, use the visible retry action. Contact support with the ledger ID and approximate request time when a settled receipt cannot be reconciled.
