Credit costs
| Generation | Credits |
|---|---|
| Lullaby (audio only) | 1 |
| Musical (audio only) | 2 |
Cover image (include_image: true, either format) | +1 |
So a lullaby with cover art costs 2 credits, and a musical with cover art costs 3.
Billing rules
- Charged on success only. Failed generations don't consume credits.
- Monthly reset. Credits reset each billing cycle: no rollover, no overage.
- At zero credits the API returns
402 Payment Required(insufficient_tokens) until renewal or upgrade.
Rate limits scale with your plan
Requests per minute and concurrent jobs are per-plan limits (table above). Exceeding them returns
429 with a Retry-After header. See the API reference.
