API PRICING
Pay per second of finished video.
Priced in credits, per model and per resolution. API prices can differ from in-app prices — a model without a separate API price follows its in-app rate (for a model with separate text and image variants, the higher of the two).
HOW BILLING WORKS
One formula, charged once, at submission.
credits_charged = max(1, ceil(round(duration × rate, 6)))
Duration × rate
A job costs its duration times the model's per-second rate at the chosen resolution, rounded up to whole credits once per job — never less than 1 credit.
Fixed at submission
The exact charge comes back as credits_charged when you submit, and it never changes afterwards.
Failed renders are refunded
Automatically and in full — no support ticket.
No overdrafts
A request your balance can't cover is rejected before anything is queued, and nothing is charged.
RATES
Credits per second, by model.
These are the rates GET /v1/models returns and POST /v1/videos charges, read live.

- Example clips use each model's default duration (or its fixed length, marked †) and assume no reference images.
- US$ figures are approximate, at the list price of a credit (7 credits = US$1). API credits are bought by API top-up at a flat rate — sign in to the top-up page to see it.
- Your key may be limited to some of these models. GET /v1/models is authoritative for what your key can call and what it costs.
- Prices can change. A job's price is fixed when it is submitted — a later change never touches a job already accepted.
