Questions

How do I call seedance-2.5?

Video generation is a job. POST /v1/videos returns a job id at once. Read GET /v1/videos/{id}?wait=60 until its status is succeeded: each answer comes as soon as the status changes, with progress and eta_seconds, or follow GET /v1/videos/{id}/events for live updates. Then download artifact.url, a link that works for an hour, or GET /v1/videos/{id}/content with your key. Videos made through the API are kept for 3 days.

Can I use the OpenAI SDK?

Not for video. OpenAI retired its own video API, and its SDK helpers expect different statuses and fields. Call the HTTP endpoints above from any language; they are three plain requests.

How is it billed?

Per second of video, at the resolution you choose. Submitting holds the price of the seconds you ask for; when the video is done Lazu charges what the provider reports and returns the rest at once, and a failed job is refunded in full. Each job shows in your usage log from the moment it is submitted, as in progress, until it settles.
