Before You Start
You’ll need:
Generate Your First Video
Set up your environment
export SEEDANCE_API_KEY="your_api_key_here"
Create a task
curl -X POST "https://seedance2-pro.com/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",
"resolution": "1280x720",
"duration": "5s"
}
}'
{
"taskId": "task_clxxxxxx"
}
A 200 response means the task was created, not completed. You must poll the status endpoint to get the final result.
Poll for completion
curl -X GET "https://seedance2-pro.com/api/v1/jobs/recordInfo?taskId=task_clxxxxxx" \
-H "Authorization: Bearer $SEEDANCE_API_KEY"
Get your video
When the task completes, the output array contains your video:{
"taskId": "task_clxxxxxx",
"model": "seedance-20",
"status": "success",
"output": [
{
"url": "https://static.seedance2-pro.com/generated/video.mp4",
"width": 1280,
"height": 720
}
]
}
