Quickstart

1. Create an account and API key

Sign up at seedanceapi.us, open Dashboard → API keys, and create a key. Copy the secret (ak_...) immediately — it is shown only once.

2. Add balance

Purchase a prepaid balance pack on the pricing page. Each generation is charged at the model list price in USD.

3. Generate a video

curl -X POST https://api.seedanceapi.us/v1/videos \
  -H "Authorization: Bearer ak_YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "seedance-2.5/text-to-video",
    "prompt": "A cinematic drone shot over misty mountains",
    "aspect_ratio": "16:9",
    "resolution": "720p",
    "duration": 5
  }'

The response is 202 Accepted with a generation id and status: pending.

4. Poll for results

curl https://api.seedanceapi.us/v1/generations/GENERATION_ID \
  -H "Authorization: Bearer ak_YOUR_API_KEY"

When status is completed, output_url contains your video.

5. Generate an image

Images return synchronously with 200 OK:

curl -X POST https://api.seedanceapi.us/v1/images \
  -H "Authorization: Bearer ak_YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "seedream-5.0/text-to-image",
    "prompt": "A serene mountain landscape at sunrise",
    "size": "2K"
  }'
