Usage

Use curl or the included helper script:

bash

# Text to video (via curl) — Seedance requires resolution
curl -X POST https://aihub-admin.aimix.pro/api-platform/v1/generations \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $PIXMIND_API_KEY" \
  -d '{"type": "video", "prompt": "ocean waves", "model": "seedance-2.0-pro", "duration": 5, "resolution": "1080p", "aspectRatio": "16:9"}'

# Sora 2 — duration MUST be 4, 8, or 12
curl -X POST https://aihub-admin.aimix.pro/api-platform/v1/generations \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $PIXMIND_API_KEY" \
  -d '{"type": "video", "prompt": "city night drive", "model": "sora-2", "duration": 8, "aspectRatio": "16:9"}'

# Veo 3.1 — only 16:9 or 9:16
curl -X POST https://aihub-admin.aimix.pro/api-platform/v1/generations \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $PIXMIND_API_KEY" \
  -d '{"type": "video", "prompt": "timelapse", "model": "veo-3.1", "duration": 8, "aspectRatio": "16:9"}'

# Or use the helper script
node {baseDir}/video-generate.js --prompt "描述文字" --model seedance-2.0-pro --duration 5 --resolution 1080p

Task Status Polling

After generation, poll for results:

bash

# Via curl
curl https://aihub-admin.aimix.pro/api-platform/v1/tasks/<TASK_ID> \
  -H "Authorization: Bearer $PIXMIND_API_KEY"

# Or use the helper script
node {baseDir}/task-status.js --task-id <TASK_ID> --poll

Response Format

Generate response:

json

{"code": 1000, "data": {"taskId": 19401, "status": "processing"}}

Task status response:

json

{
  "code": 1000,
  "data": {
    "taskId": 19401,
    "status": "ready",
    "progress": 100,
    "videoUrl": "https://chatmix.top/...",
    "coverUrl": "https://chatmix.top/..."
  }
}

• data.taskId — Use this to poll status
• Status values: processing → ready (success)
• On success: data.videoUrl contains the video URL, data.coverUrl has the cover image

Error Responses

• code: 400 with 不支持的模型: <model> — Unsupported model slug.
• code: 500 with the parameter resolution specified in the request is not valid for model <X> — Seedance models require an explicit resolution of 480p, 720p, or 1080p.
• code: 500 with Invalid aspect ratio: <X> — Aspect ratio not supported by this model. Veo only accepts 16:9 / 9:16.
• code: 500 with invalid duration: <N>s (model sora-2-preview only supports duration=[4 8 12]) — Sora only accepts durations of 4, 8, or 12 seconds.
• code: 1001 with 请输入提示词 — Empty prompt.
• code: 1001 with 速率限制：每minute最多60次请求 — Rate limited; back off.

Guidelines

1. Always confirm the prompt, duration, and model with the user before generating
2. Default to seedance-2.0-pro with resolution: 1080p and aspectRatio: 16:9 unless user specifies otherwise
3. Seedance models require resolution (480p / 720p / 1080p) — requests without it fail
4. Veo models only accept 16:9 or 9:16 aspect ratios
5. Sora 2 models only accept duration of 4, 8, or 12 seconds — pick one of these explicitly
6. If user provides a reference image, automatically use img2video mode and pick an image-to-video capable model (wan2.6-i2v, wan2.6-i2v-flash, or any Veo / Sora / Seedance model)
7. Video generation takes longer than images — use --poll with appropriate interval (recommend 5–10s)
8. After getting the task ID, poll until completion and return video URL
9. For faster results on a budget, prefer seedance-2.0-fast, wan2.6-i2v-flash, or veo-3.0-fast
10. Avoid probing the API by sending requests with arbitrary model names — many slugs that appear in the marketing site are not actually exposed by the API. Stick to the table above.
