Billing

Every plan includes a monthly credit allowance that resets each billing cycle: no rollover, no overage. The Free plan includes 10 credits so you can build and test before upgrading. See Pricing for the full plan comparison.

Credits are charged on success only. Failed generations never cost you anything. A lullaby costs 1 credit, a musical 2 credits, and the optional cover image adds +1. When your monthly credits run out the API returns 402 until the cycle renews or you upgrade.

Paid plans are billed monthly by card through Stripe. Upgrade or downgrade any time from the Dashboard; changes take effect immediately and are prorated for the rest of the cycle. Enterprise plans support custom volumes, invoicing, and terms.
