Why developers choose Kinovi:
  • Real person mode built-in — generate videos with real human faces by default, no extra setup or permissions needed
  • Battle-tested at scale — 500K+ videos generated in production, with auto-retry and failure recovery built in
  • Output-only billing — you only pay for the video you get. Reference video/audio length doesn’t affect your cost
  • No preprocessing needed — upload any image, video, or audio as-is. We handle resizing, format conversion, duration trimming, and aspect ratio automatically
  • Up to 50 concurrent tasks — other platforms typically cap at ~10. Scale your pipeline without bottlenecks
  • 480p / 720p / 4K — 720p by default, outputResolution for 480p (half price), upscaleResolution for 4K

​
2. Create a Task

curl -X POST "https://kinovi.ai/api/v1/jobs/createTask" \
  -H "Authorization: Bearer $SEEDANCE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "seedance-20",
    "inputs": {
      "prompt": "A serene Japanese garden with cherry blossoms swaying in the wind",
      "duration": "5",
      "aspectRatio": "16:9"
    }
  }'
Returns: 
{ "taskId": "task_clxxxxxx" }
A 200 response means the task was created, not completed. You need to poll for the result.

​
3. Poll for Result

Video generation takes 1–5 minutes. Poll every 5 seconds until status is success or fail: 
curl -s "https://kinovi.ai/api/v1/jobs/recordInfo?taskId=YOUR_TASK_ID" \
  -H "Authorization: Bearer $SEEDANCE_API_KEY"
Success response: 
{
  "taskId": "task_clxxxxxx",
  "status": "success",
  "output": [{ "url": "https://..../video.mp4", "width": 1280, "height": 720 }],
  "creditsUsed": 200
}

​
That’s It

3 steps: create task → poll status → get video URL. A 5-second 720P video costs 200 credits ($1.00).
