Request Parameters

modelstringrequired
Model name. The model code includes model type, resolution, and whether video reference is used.
  • sd_2.0_discount_480p
  • sd_2.0_discount_720p
  • sd_2.0_discount_1080p
  • sd_2.0_discount_480p_with_video_ref
  • sd_2.0_discount_720p_with_video_ref
  • sd_2.0_discount_1080p_with_video_ref
  • sd_2.0_fast_discount_480p
  • sd_2.0_fast_discount_720p
  • sd_2.0_fast_discount_480p_with_video_ref
  • sd_2.0_fast_discount_720p_with_video_ref
When using a _with_video_ref model, content must include a video_url item with role=reference_video.
resolutionstring
Optional. The full model code already includes resolution. If provided, it must match the resolution in model.
ratiostring
Aspect ratio. Default: 16:9. Supported values: 16:9, 9:16, 1:1, 4:3, 3:4, 21:9, adaptive.
durationinteger
Duration in seconds. Default: 5. Range: 4-15.
generate_audioboolean
Whether to generate audio. Default: true.
return_last_frameboolean
Whether to return the last-frame image. Default: false. When set to true and the task generates a last frame, read last_frame_url from the query API.
toolsarray
Tool configuration. Default: not sent. Currently only the Seedance 2.0 web search tool is exposed: {"type":"web_search"}.
tools[].typestring
Tool type. Currently supported value: web_search. Other tool types are not supported.
seedinteger
Random seed. Default: -1, which lets the model service choose a random seed. A fixed value improves reproducibility, but generation is still probabilistic.
contentarrayrequired
Content array. One type=text prompt is required.
content[].typestringrequired
text, image_url, video_url, or audio_url.
content[].textstring
Required when content[].type=text. The text prompt.
content[].rolestring
first_frame, last_frame, reference_image, reference_video, or reference_audio.
content[].image_url.urlstring
Image URL. Public URL or uploaded asset reference: assetId://{assetId}. Base64 input is not supported.
content[].video_url.urlstring
Video URL. Public URL or uploaded asset reference: assetId://{assetId}.
content[].audio_url.urlstring
Audio URL. Public URL or uploaded asset reference: assetId://{assetId}. Base64 input is not supported.
For real-person or avatar media, upload the asset first and confirm that its status is ACTIVE through the asset detail API before referencing it with assetId://{assetId} and creating a task. Do not create a task while the asset is in any other status.

Unsupported Fields

The edition-specific API currently does not pass through callback_url, priority, safety_identifier, service_tier, execution_expires_after, frames, camera_fixed, watermark, or draft. Do not depend on these fields in requests. If they are exposed later, this documentation will state it explicitly.

Media And Scenario Limits

  • Text prompt: Chinese prompts should be within 500 characters, and English prompts within 1000 words.
  • Image input: jpeg, png, webp, bmp, tiff, gif, heic, and heif are supported. Each image must be under 30 MB, with aspect ratio (0.4, 2.5) and width/height (300px, 6000px).
  • Image counts: first-frame mode uses 1 image; first-and-last-frame mode uses 2 images with first_frame and last_frame; multi-modal reference mode uses 1-9 reference_image items.
  • Video input: mp4 and mov are supported. Each video must be [2, 15] seconds, up to 3 reference videos, with total video duration no more than 15 seconds; each video must be under 50 MB, with FPS [24, 60].
  • Audio input: wav and mp3 are supported. Each audio item must be [2, 15] seconds, up to 3 reference audio items, with total audio duration no more than 15 seconds; each audio item must be under 15 MB.
  • Scenario exclusivity: first-frame, first-and-last-frame, and multi-modal reference scenarios cannot be mixed. Audio cannot be provided alone; include at least one reference image or video.
  • This system does not support image/audio base64 input. Use a public URL or an assetId returned by the asset upload API.
