What this API does

Create a 4–30 second Seedance 2.5 video at 480p or 720p using the prompt and references shown in the input schema. Native audio is included. Reserve the maximum output-token charge, then pay only for the generated output tokens after the video has been preserved as a Scrollport artifact. Failed requests are uncharged. The same job resumes after interruption. The model rejects reference images containing real human faces. Video references are excluded.
