[excited] Hello! Welcome to Eleven v4.

价格

单价 $0.08 / 千字符

按输入文本字符数计费，每 1,000 字符计价，按实际长度折算（空格、标点和标签都计入）。

每次请求按本次文本的字符数临时冻结相应费用（每 1,000 字符 $0.08，按 Unicode 字符计数，最少按 1 个字符计；最长文本最多 $0.40；请求带有未声明的字段，或其他超过 64 个字符的自由文本时，冻结 $0.40），按实际用量扣费，通常在一分钟内完成：多余部分退回，超出部分从余额扣除，余额可能因此变为负数；余额为负时新请求暂停，充值后先抵扣欠款。

例如：100 个字符冻结 $0.008，1,000 个字符冻结 $0.08。

余额需不低于 $0.01，且足以支付本次冻结。

生成失败不收费。

返回结果

接口会返回生成结果，或返回可轮询的异步任务；具体响应方式与结果字段见下方示例和 Schema。

异步任务

提交响应

HTTP 202

/v1/model-tasksapplication/json

{
  "id": "task_example",
  "model": "elevenlabs/eleven-v4",
  "status": "queued"
}

状态响应

HTTP 200

/v1/model-tasks/{id}application/json

{
  "id": "task_example",
  "model": "elevenlabs/eleven-v4",
  "status": "completed",
  "output": {
    "audio": {
      "url": "https://api.musespan.com/v1/model-tasks/task_example/artifacts/0"
    }
  }
}

文件下载

HTTP 200

/v1/model-tasks/{id}/artifacts/{index}生成的音频（如 audio/mpeg）

任务完成后，output 里的文件地址就指向此接口，序号从 0 开始。下载时要带上同一个 API Key（Authorization 请求头）。

错误响应

HTTP 400

/v1/model-tasksapplication/json

{
  "error": {
    "code": "invalid_input",
    "message": "The input does not match this model's input schema. Check the model's API documentation.",
    "type": "invalid_request_error"
  }
}

调用示例

异步任务提交后返回任务 ID，轮询至 status 为 completed 后，按返回结果获取生成内容。API Key 在控制台获取。

# Use a new directory for each new generation. Rerunning here continues this task.
