# 生成音乐

>  - 从提示词生成歌曲：`custom=false` 为灵感模式（`prompt` 作灵感提示词），`=true` 为自定义模式（`prompt` 作歌词）。
- 异步任务：提交返回 `task_id`，轮询 `GET /v1/music/tasks/:task_id` 获取结果 

> [!WARNING]
>
> `custom` 决定文本字段是否生效：`custom=true`（自定义）时 `prompt` 作歌词，`title`、`style`、`negative_tags`、`auto_lyrics` 和 `persona_id` 生效；`custom=false`（灵感）时 `prompt` 作灵感描述，上述自定义字段被忽略。`style_weight`、`weirdness_constraint`、`audio_weight` 和 `vocal_gender` 在两种模式下都会校验并生效。

> [!NOTE]
>
> 本端点的字段名与其他端点略有不同：使用 `style`，而不是 `tags`。

## Authorizations

**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
```

## Body

**model** `string` (default: suno)

音频模型。当前传 `suno`（不传默认 `suno`）。

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

`false`=灵感模式；`true`=自定义模式（`prompt` 作歌词）。默认 `false`。

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

`true`=纯音乐、无人声。默认 `false`。

**version** `string`

公共版本：`v6` / `v6-wild` / `v6-mini`。与 `custom_model_id` 至少提供一个；使用自定义模型时省略本字段。

**custom\_model\_id** `string`

创建自定义模型任务返回的完整 UUID。与 `version`、`persona_id` 互斥；提供本字段后按自定义模型价格档计费。

**prompt** `string`

灵感提示词 / 歌词。**`custom=false` 时必填**且不超过 3000 个字符；`custom=true` 且 `instrumental=false` 时**必填**且不超过 5000 个字符；自定义纯音乐可省略。

**title** `string`

标题（自定义模式），不超过 80 个字符。**`custom=false`（灵感模式）时忽略**。

**style** `string`

风格标签（自定义模式），不超过 1000 个字符。**`custom=false`（灵感模式）时忽略**。

**negative\_tags** `string`

负向风格标签（不希望出现的风格）。**仅 `custom=true` 时生效**。

**auto\_lyrics** `boolean`

`true`=对输入歌词进行二次创作。**仅 `custom=true` 时生效**。

**persona\_id** `string`

Persona 风格 ID。**仅 `custom=true` 时生效**，与 `custom_model_id` 互斥。

**vocal\_gender** `string`

人声性别：`Male` / `Female`（也接受 `m` / `f` / `male` / `female`，后端自动归一）。**两种模式均生效**。

**style\_weight** `number`

风格权重，`0.00`–`1.00`。两种模式下都会校验并生效。

**weirdness\_constraint** `number`

创意度，`0.00`–`1.00`。两种模式下都会校验并生效。

**audio\_weight** `number`

音频权重，`0.00`–`1.00`。两种模式下都会校验并生效。

**variety** `string`

风格变化程度：`off` / `normal` / `high` / `extra` / `max`。可省略，没有固定默认值。

**max\_mode** `boolean` (default: false)

是否启用 Max 模式。启用时要求 `custom=true`，并按普通售价的 2 倍计费。

**audio\_format** `string`

输出音频格式：`mp3` / `m4a` / `wav`。省略时由服务自动选择。

**duration** `integer`

目标生成时长，范围 10–360 秒，仅 `custom=true` 时可用。实际成品时长以任务结果为准。

> [!NOTE]
>
> **获取结果**：本接口为异步任务。提交后拿到 `task_id`，按 3–5s 间隔轮询 `GET /v1/music/tasks/{task_id}`，直到 `status` 为 `completed` 或 `failed`（音乐生成通常 30–120s；生成中 `status` 可能为 `pending` 或 `processing`，`progress` 为 0–100 的整数且不保证按固定节点变化）。完成后在 `data.result.music[]` 取 `audio_url`（另有 `image_url` / `video_url` / `title` / `duration` 等）。失败时 `data.error.message` 为原因，自动退回预扣额度。

## Response

**code** `integer`

响应状态码

**data** `array`

返回数据数组

**属性**

**status** `string`

任务状态

* `submitted` - 已提交

**task\_id** `string`

任务唯一标识符（用于轮询 `GET /v1/music/tasks/{task_id}` 获取结果）
