Poll `GET /videos/generations/{task_id}` with the returned `task_id` until the task reaches a terminal state. If the POST request times out or its result is uncertain, do not blindly retry it. The original request may already have created another task and billing order. Completed asset URLs are dynamically signed. Download or copy assets that must be retained instead of treating the URLs as permanent identifiers. operationId: seedance-2-0-mini requestBody: required: true content: application/json: schema: type: object properties: prompt: type: string maxLength: 5000 description: Required for text-to-video; optional for image-to-video. first_frame_image: type: string format: url description: >- Optional image-to-video start frame; cannot be combined with reference images, videos or audios. last_frame_image: type: string format: url description: >- Optional end frame; requires first_frame_image and cannot be combined with reference media. images: type: array maxItems: 9 items: type: string format: url description: >- Up to 9 reference image URLs; cannot be combined with first or last frame. videos: type: array maxItems: 3 items: type: string format: url description: >- Up to 3 reference video URLs; cannot be combined with first or last frame. audios: type: array maxItems: 3 items: type: string format: url description: >- Up to 3 reference audio URLs; requires at least one reference image or video and cannot be combined with first/last frame. resolution: type: string enum: - 480P - 720P default: 720P description: 'Must be one of: 480P, 720P.
