Seedance 2.0 Save Fast API capabilities

Save Fast is the constrained iteration route: it uses the accelerated Seedance variant while excluding real human faces from prompts and references. ^[1][2][3]

Rapid eligible-subject drafts

Use it to iterate on products, environments, animation, abstract visuals, and fictional subjects before selecting a final prompt. ^[2][3]

No real-face workflows

The Save restriction applies even though the underlying Fast route can otherwise handle broader Seedance inputs. ^[3]

Seedance family direction

Prompts can still describe motion, camera language, lighting, story progression, and synchronized sound associated with the Seedance 2.0 family. ^[1][2]

Shared asynchronous lifecycle

Creation and polling use the same APINEED video endpoints, with seconds and metadata assembled from explicit controls. ^[3]

Fast iteration without real-person inputs

Validate eligibility first. Remove real-person identity requirements before iterating on motion or style.

Compare accepted outputs. Track usable clips and retries, not only the time of the first response.

Escalate deliberately. Use Fast or standard Seedance when a real face is needed; use standard Save when final quality deserves a separate pass.

Quick Start

Call Seedance 2.0 Save Fast with the verified APINEED endpoint and model-specific request shape.

Create an API key

Store your APINEED key server-side as API_NEED_API_KEY.

export API_NEED_API_KEY=sk-apineed-v1-...

Send the request

Use seedance-2.0-fast:save with POST /v1/videos.

curl https://apineed.com/v1/videos \
  -H "Authorization: Bearer $API_NEED_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
  "model": "seedance-2.0-fast:save",
  "prompt": "A cinematic 5-second product shot with stylized fictional characters, soft studio light, controlled camera movement, and no real human faces.",
  "seconds": "5",
  "metadata": {
    "resolution": "720p",
    "ratio": "16:9",
    "generate_audio": false,
    "watermark": false
  }
}'

Poll the task

Save task_id, then poll GET /v1/videos/{task_id} every few seconds until the task is completed or failed.

curl https://apineed.com/v1/videos/$TASK_ID -H "Authorization: Bearer $API_NEED_API_KEY"
