What this API does

Create a 480p or 720p Seedance 2.5 clip from text, with explicit duration and aspect ratio for an exact pre-run hold. The MP4 is persisted privately and the provider receives only a stable pseudonymous account identifier.

Agents select this operation with tool ID bytedance.seedance-2-5-text-to-video, then inspect its current executable contract before a run.
