Seedance 2.0 Mini API quickstart

Create a Seedance 2.0 Mini job, then wait for it. Set KREATORFLOW_API_KEY on your server first.

curl https://kreatorflow.ai/v1/videos \
  -H "Authorization: Bearer $KREATORFLOW_API_KEY" \
  -H "Content-Type: application/json" \
  -H "Idempotency-Key: perfume-teaser-001" \
  -d '{
    "model": "kreator-video-mini",
    "prompt": "slow dolly in on a glass perfume bottle on wet black stone, soft studio light, light rain",
    "duration": 5,
    "aspect_ratio": "9:16",
    "resolution": "720p"
  }'

# then poll until status is completed, failed, canceled or blocked
curl https://kreatorflow.ai/v1/jobs/JOB_ID \
  -H "Authorization: Bearer $KREATORFLOW_API_KEY"

Rather not poll? Add webhook_url to the request and KreatorFlow calls it when the job finishes, signed so you can check it came from us. See AI video API webhooks and the Seedance API quickstart.

GET /v1/models returns the same limits for every model, so your code can read them instead of hard-coding them. Every field, the job object, webhooks and error codes are in the Seedance API reference.

How to write Seedance 2.0 Mini prompts

  • Mini works best on simple, single-action shots: a pet, an object, one person moving.
  • Render many short variants and keep the best, then re-render the winner on Seedance 2.0 if it needs more detail.
  • Keep the camera simple (static or one slow move) for the cleanest results at this price.
  • Batch through the API with an Idempotency-Key per variant so a resent request never doubles a charge.

What to use the Seedance 2.0 Mini API for

  • High-volume pipelines and previews
  • Drafts and storyboards
  • A/B variants at the lowest price per clip

Seedance 2.0 Mini API limitations

  • Clips run from 4 to 10 seconds per request; longer videos are several clips joined in your own pipeline.
  • The highest resolution is 1080p. For 4K, use Seedance 2.0 or Seedance 2.5.
  • References of real people, celebrities or public figures are declined, and a declined job is not charged.
  • The output link needs your API key and expires, so copy each finished file to your own storage.
  • Generation takes time: poll every 10 to 15 seconds or use a webhook rather than holding a request open.
