## 认证

**Authorization** `string` *required*

所有接口均需要使用 Bearer Token 进行认证

获取 API Key：

访问 [API Key 管理页面](https://apimart.ai/keys) 获取您的 API Key

使用时在请求头中添加：

```
Authorization: Bearer YOUR_API_KEY
```

## 请求参数

**model** `string` *required*

支持以下模型：

* `MiniMax-Hailuo-2.3` - Hailuo 2.3 模型
* `MiniMax-Hailuo-2.3-Fast` - Hailuo 2.3 Fast 模型（更快速度）

> [!WARNING]
>
> **MiniMax-Hailuo-2.3-Fast**：\\
>
> 使用该模型时，`first_frame_image` 参数必须上传

**nsfw\_check** `boolean` (default: false)

是否在提交视频任务前执行内容审核。

* `true`：使用 `omni-moderation-latest` 审核提示词和输入图片
* `false` 或不传：不发起审核请求，不增加审核成本与延迟（默认）

**prompt** `string` *required*

视频内容描述（最多 2000 字符）

建议详细描述场景、动作、风格等，以获得更好的生成效果。支持运镜指令（详见下方运镜指令说明）。

示例：`"一只可爱的猫咪在草地上奔跑"`

**duration** `integer` (default: 6)

视频时长（秒）

可选值：

* `6` - 6秒视频
* `10` - 10秒视频

默认值：`6`

> [!WARNING]
>
> **1080p 限制**：使用 1080p 分辨率时，仅支持 6 秒时长

**resolution** `string` (default: 768p)

视频分辨率

可选值：

* `768p` - 高清
* `1080p` - 全高清（仅支持 6 秒时长）

默认值：`768p`

**first\_frame\_image** `string`

视频起始帧图片

支持两种格式：

* **公网 URL**：`https://example.com/start.jpg`
* **Base64 编码**：`data:image/jpeg;base64,/9j/4AAQSkZJRgABAQEAYABg...`

传入后将以该图片作为视频的起始画面

> [!WARNING]
>
> **MiniMax-Hailuo-2.3-Fast**：\\
>
> 使用该模型时，`first_frame_image` 参数必须上传

**prompt\_optimizer** `boolean` (default: true)

是否自动优化 prompt

启用后，系统会自动优化您的提示词以获得更好的生成效果

默认值：`true`

**fast\_pretreatment** `boolean` (default: false)

是否缩短 prompt 优化耗时

启用后可加快处理速度，但可能略微影响优化效果

默认值：`false`

**watermark** `boolean` (default: false)

是否添加水印

默认值：`false`

## 分辨率与时长组合

| 分辨率 | 支持的时长 | 备注 |
| - | - | - |
| 768p | 6秒、10秒 | 全部支持 |
| 1080p | 6秒 | 不支持10秒 |

## 运镜指令

在 `prompt` 中使用 `[指令]` 语法控制运镜效果，支持以下 15 种指令：

| 类别 | 指令 |
| - | - |
| 平移 | `[左移]` `[右移]` |
| 左右摇 | `[左摇]` `[右摇]` |
| 推拉 | `[推进]` `[拉远]` |
| 升降 | `[上升]` `[下降]` |
| 上下摇 | `[上摇]` `[下摇]` |
| 变焦 | `[变焦推近]` `[变焦拉远]` |
| 其他 | `[晃动]` `[跟随]` `[固定]` |

**使用示例**：

```json theme={null}
{
  "model": "MiniMax-Hailuo-2.3",
  "prompt": "[推进]一只猫咪在花园中奔跑，镜头缓缓推进特写"
}
```

## 响应

**code** `integer`

响应状态码，成功时为 200

**data** `array`

返回数据数组

**数组元素**

**status** `string`

任务状态，初始提交时为 `submitted`

**task\_id** `string`

任务唯一标识符，用于查询任务状态和结果

## 使用场景

### 场景 1：快速生成文本视频

```json theme={null}
{
  "model": "MiniMax-Hailuo-2.3",
  "prompt": "一只可爱的猫咪在草地上奔跑，阳光明媚"
}
```

### 场景 2：生成高质量 1080p 视频

```json theme={null}
{
  "model": "MiniMax-Hailuo-2.3",
  "prompt": "城市夜景，霓虹灯闪烁，车流穿梭",
  "duration": 6,
  "resolution": "1080p",
  "prompt_optimizer": true,
  "watermark": false
}
```

### 场景 3：指定首帧图片生成视频

```json theme={null}
{
  "model": "MiniMax-Hailuo-2.3",
  "prompt": "小猫跑向镜头，微笑着眨眼",
  "first_frame_image": "https://example.com/cat.jpg",
  "duration": 6,
  "resolution": "1080p"
}
```

### 场景 4：使用运镜指令

```json theme={null}
{
  "model": "MiniMax-Hailuo-2.3",
  "prompt": "[推进]一只猫咪在花园中奔跑，镜头缓缓推进特写",
  "duration": 6,
  "resolution": "768p"
}
```

### 场景 5：快速预处理模式

```json theme={null}
{
  "model": "MiniMax-Hailuo-2.3",
  "prompt": "海浪拍打沙滩，日落时分",
  "duration": 10,
  "resolution": "768p",
  "prompt_optimizer": true,
  "fast_pretreatment": true
}
```

> [!NOTE]
>
> **查询任务结果**
>
> 视频生成为异步任务，提交后会返回 `task_id`。使用 [获取任务状态](/cn/api-reference/tasks/status.md) 接口查询生成进度和结果。
