Doubao Seedance 2.5 Draft API Documentation

MixRoute lists doubao-seedance-2-5-260628-draft as a separate Seedance 2.5 Draft route. Use the complete ID, including -draft; it is a MixRoute route identifier, not a replacement name for the regular Doubao or Dreamina model. Draft previews help check scene composition and motion before producing a final video. Use 480p for Draft requests; do not apply the regular route’s 720p or 1080p output settings to this Draft example.

Model Information

Field	Description
Model ID	`doubao-seedance-2-5-260628-draft`
Endpoint	`POST /v1/video/generations`
Draft resolution	`480p`

Request Layout

Keep model, prompt, and asset at the root. Put draft, content, and all generation settings inside metadata. The example explicitly sets metadata.draft: true; it does not rely on an implicit default from the model suffix.

Field	Description
`prompt`	Video prompt; keep it identical to the text item in metadata.content.
`asset`	Use false for the text-only example.
`metadata.content`	Input array; include a type=text item for text-only generation.
`metadata.draft`	Set true for this Draft request.
`metadata.resolution`	Set 480p for Draft output.
`metadata.duration`	Requested seconds. This example uses 4.
`metadata.ratio`	Output aspect ratio. This example uses 9:16.
`metadata.generate_audio`	This example uses false for silent video.

Request Example

Set MIXROUTE_API_KEY before running the request. Submission creates a billable asynchronous task; do not automatically resubmit after a client timeout.

curl --request POST "https://api.mixroute.ai/v1/video/generations" \
  --header "Authorization: Bearer $MIXROUTE_API_KEY" \
  --header "Content-Type: application/json" \
  --data '{
  "model": "doubao-seedance-2-5-260628-draft",
  "prompt": "A red ceramic mug slowly rotates on a white tabletop. Static camera, soft studio lighting.",
  "asset": false,
  "metadata": {
    "content": [
      {
        "type": "text",
        "text": "A red ceramic mug slowly rotates on a white tabletop. Static camera, soft studio lighting."
      }
    ],
    "draft": true,
    "resolution": "480p",
    "duration": 4,
    "ratio": "9:16",
    "generate_audio": false
  }
}'

Query the Task

Replace MIXROUTE_TASK_ID with the MixRoute task ID returned by submission. Wait for a successful terminal status before reading the video URL; a successful submission alone does not mean generation is complete.

curl "https://api.mixroute.ai/v1/video/generations/MIXROUTE_TASK_ID" \
  --header "Authorization: Bearer $MIXROUTE_API_KEY"

Task statuses and result fields The regular model doubao-seedance-2-5-260628 and the Dreamina model dreamina-seedance-2-5-260628 remain separate entries. Use the route-specific documentation instead of changing prefixes or removing the suffix. Doubao API parameters | Regular Doubao Seedance 2.5
