Introduction
Nebula Lab V4 API uses a points-based billing model.Billing Notes
- Points are deducted when a task is submitted successfully (some video APIs use pre-deduction; points are finalized only after the task succeeds).
- Duration-based APIs support formats such as
3s、5s、8s、10s、12s; points are calculated from the duration converted to seconds. - Points are rounded to 1 decimal place.

Deduction and Pre-deduction
- Immediate deduction: Most image generation, image-to-video (traditional / first-last frame), and object transfer creative/dressing mode—points are deducted from the account when the submit request succeeds.
- Pre-deduction: Text to video, image-to-video face swap, object transfer standard mode, and object transfer dressing mode—a “unpaid” points record is created on submit; it is marked as paid only after the task succeeds (e.g., query shows success or callback succeeds). If the task fails, points may not be charged or may be refunded per business logic.
