Seedance 2.0 API is Now Live

We're excited to announce that the Seedance 2.0 API is now available at seedance2.ink!

Developers can now integrate our powerful multimodal AI video generation capabilities directly into their applications. Whether you're building a content creation platform, an automated video production tool, or any application that needs high-quality AI-generated videos, our API makes it simple.

🚀 Getting Started in 3 Steps

1. Get Your API Key

After registering at seedance2.ink, navigate to your dashboard and generate an API key. Each key is unique to your account and secures your API requests.

2. Make Your First Request

Here's a simple text-to-video generation request:

curl -X POST https://seedance2.ink/api/open/v1/video/generations \
  -H "Authorization: Bearer sk_live_your_api_key" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "seedance-2.0",
    "input": {
      "prompt": "A neon-lit alley in heavy rain, cinematic tracking shot",
      "ratio": "16:9",
      "duration": 5,
      "resolution": "720p"
    }
  }'

3. Check the Result

The API returns a requestId immediately. Use it to poll for completion:

curl https://seedance2.ink/api/open/v1/video/generations/{requestId} \
  -H "Authorization: Bearer sk_live_your_api_key"

When status is "SUCCESS", the result.urls array contains your generated video URLs.

💰 Pricing

Simple, transparent pricing based on video duration:

Example: A 5-second 720p video with Seedance 2.0 costs $0.50

Charges are calculated as rate × duration and deducted from your account balance when the generation completes successfully.

📡 API Endpoints

Create Generation Task

POST /api/open/v1/video/generations

Submit a video generation request. The response includes a requestId for tracking.

Query Task Status

GET /api/open/v1/video/generations/{requestId}

Retrieve the current status and result of your generation task.

🎬 Supported Modes

Seedance 2.0's multimodal engine automatically selects the generation mode based on your input materials.

Text to Video

Omit mediaUrls to generate from pure text:

{
  "model": "seedance-2.0",
  "input": {
    "prompt": "A dragon soaring over snow-capped mountains at sunset",
    "ratio": "16:9",
    "duration": 8,
    "resolution": "1080p"
  }
}

Image to Video - First Frame

Provide one image to use as the starting frame:

{
  "model": "seedance-2.0",
  "input": {
    "prompt": "The candle flickers and goes out",
    "mediaUrls": ["https://example.com/cake-with-candles.jpg"],
    "ratio": "16:9",
    "duration": 5,
    "resolution": "720p"
  }
}

Image to Video - First & Last Frame

Provide two images to define both start and end frames:

{
  "model": "seedance-2.0",
  "input": {
    "prompt": "Transform gradually",
    "mediaUrls": [
      "https://example.com/image-start.jpg",
      "https://example.com/image-end.jpg"
    ],
    "ratio": "16:9",
    "duration": 5,
    "resolution": "720p"
  }
}

Multimodal Reference (Seedance 2.0 Exclusive)

Mix images, videos, and audio. Use @1, @2, @3 in your prompt to reference materials by position:

Image + Audio - Generate a video where movement syncs with music:

{
  "model": "seedance-2.0",
  "input": {
    "prompt": "@1 dances to the rhythm of @2",
    "mediaUrls": [
      "https://example.com/dancer.jpg",
      "https://example.com/music.mp3"
    ],
    "ratio": "16:9",
    "duration": 8,
    "resolution": "720p"
  }
}

Image + Video - Use a video as motion reference:

{
  "model": "seedance-2.0",
  "input": {
    "prompt": "@1 performs the action shown in @2",
    "mediaUrls": [
      "https://example.com/character.jpg",
      "https://example.com/reference-motion.mp4"
    ],
    "ratio": "16:9",
    "duration": 5,
    "resolution": "720p"
  }
}

⏱️ What to Expect

Asynchronous Processing: All video generations are processed asynchronously. You'll receive a requestId immediately—no long-running connections to manage.

Queue Times: Current processing times vary by load:

Generation itself typically takes 1–3 minutes depending on duration and resolution.
