Quick start

curl -X POST https://api.acedata.cloud/minimax/videos \
  -H "Authorization: Bearer $ACEDATACLOUD_API_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "minimax-h3",
    "prompt": "A red fox running through a snowy forest at dawn, low tracking shot",
    "resolution": "768P",
    "ratio": "16:9",
    "duration": 4,
    "async": true
  }'

Poll the returned task_id:

curl -X POST https://api.acedata.cloud/minimax/tasks \
  -H "Authorization: Bearer $ACEDATACLOUD_API_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"action":"retrieve","id":"TASK_ID"}'

Modes

The API does not accept action. It infers the mode:

1. audio_urls present with images → audio-guided video
2. otherwise image_urls present → image-to-video
3. otherwise prompt-only → text-to-video

prompt is required in every mode; audio requires at least one image.

Public pricing is $0.057143/s for 768P and $0.091429/s for 2K on the largest package. Failed tasks are not charged.
