默认设置（质量 high、1024×768、1 张）约 $0.037 / 张；质量、尺寸、张数越高，用量越多。

每次请求会先临时冻结 $0.0367，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。

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": "openai/gpt-image-2.5-sunburst/text-to-image",
  "status": "queued"
}
状态响应
HTTP 200
/v1/model-tasks/{id}application/json
{
  "id": "task_example",
  "model": "openai/gpt-image-2.5-sunburst/text-to-image",
  "status": "completed",
  "output": {
    "images": [
      {
        "url": "https://api.musespan.com/v1/model-tasks/task_example/artifacts/0"
      }
    ]
  }
}
文件下载
HTTP 200
/v1/model-tasks/{id}/artifacts/{index}生成的图片（如 image/png）

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。
