# 獲取 3D 模型狀態

> 獲取 3D 生成任務的狀態與結果

輪詢此端點以檢查您的 3D 模型生成任務狀態。

<Info>
  如果建立回應中包含 `poll_url`，請優先直接呼叫該 URL 輪詢。`id` 與 `task_id` 應視為同一個非同步任務身分。

  如果該任務已不存在，或無法再從公開任務記錄中查詢到，TokenLab 會回傳 `async_task_not_found`，並附上訊息 `Task not found or no longer available.`
</Info>

## 路徑參數

<ParamField path="id" type="string" required>
  3D 生成任務 ID。
</ParamField>

## 回應

<ResponseField name="id" type="string">
  任務 ID。
</ResponseField>

<ResponseField name="task_id" type="string">
  可用時返回的非同步任務 ID 別名。
</ResponseField>

<ResponseField name="status" type="string">
  任務狀態：`pending`、`processing`、`completed` 或 `failed`。
</ResponseField>

<ResponseField name="progress" type="integer">
  可選進度值。僅在任務提供真實進度時返回；請使用 `status` 判斷任務是否完成。
</ResponseField>

<ResponseField name="model_url" type="string">
  下載 3D 模型檔案的 URL（完成時）。
</ResponseField>

<ResponseField name="glb_url" type="string">
  下載 GLB 格式模型的 URL（可用時）。
</ResponseField>

<ResponseField name="fbx_url" type="string">
  下載 FBX 格式模型的 URL（可用時）。
</ResponseField>

<ResponseField name="error" type="string">
  錯誤訊息（失敗時）。
</ResponseField>
