Magick API 用户指南

通过统一视频任务接口调用 Veo 模型；说明当前项目中的可用模型、请求字段和查询方式。

提交路由：POST /v1/videos
任务查询：GET /v1/videos/{task_id}
内容下载：GET /v1/videos/{task_id}/content

旧版兼容路由 POST /v1/video/generations 和 GET /v1/video/generations/{task_id} 仍存在；新接入建议使用体验中心和模型端点中展示的 /v1/videos。

提交请求示例

cURL

curl --request POST \
  --url https://api.magickapi.com/v1/videos \
  --header 'Authorization: Bearer YOUR_API_KEY' \
  --header 'Content-Type: application/json' \
  --data '{
    "model": "veo-3.1-fast-generate-preview",
    "prompt": "海豚在碧蓝海洋中跳跃",
    "duration": 8,
    "size": "1280x720",
    "images": [
      "https://example.com/first-frame.png"
    ],
    "metadata": {
      "generateAudio": true,
      "seed": 7
    }
  }'

提交成功响应示例

提交路由返回的是公开 task_id 对应的 OpenAI 风格视频对象：

{
  "id": "task_01KXYZ1234567890ABCDE",
  "task_id": "task_01KXYZ1234567890ABCDE",
  "object": "video",
  "model": "veo-3.1-fast-generate-preview",
  "status": "queued",
  "progress": 0,
  "created_at": 1712345678
}

当前项目真正解析的公共顶层字段

size

metadata

Veo 相关参数写法

`size`

对于 Veo，建议直接传像素尺寸，例如：

1280x720
720x1280
3840x2160

项目会根据 size 自动推导默认 resolution 和 aspectRatio。

`metadata`

Veo 扩展参数应放进 metadata，例如：

aspectRatio
resolution
negativePrompt
seed
generateAudio

旧版兼容查询

旧版任务查询路由仍可使用：

curl https://api.magickapi.com/v1/video/generations/task_01KXYZ1234567890ABCDE \
  -H 'Authorization: Bearer YOUR_API_KEY'
