使用這個端點可根據 Prompt 建立一個 Kling 的文字轉影片任務。它會啟動非同步工作，而不是立即回傳完成的影片。

​
第一個可運作的請求

  • 先傳送簡短的 Prompt
  • 僅在基本流程可正常運作後，再加入 aspect_ratio、duration 或 mode
  • 如果你想使用推送交付而非純輪詢，請設定 callback_url

​
任務流程

1

提交生成請求

透過這個端點建立任務，並儲存回傳的 Kling task id。
2

輪詢任務狀態

透過單筆查詢檢查進度，直到任務進入終態。
3

保存結果

當 Kling 回傳完成的資產中繼資料後，如果你需要長期保留，請將結果移轉到你自己的儲存空間。
如需完整的參數矩陣與 model-track 詳細資訊，請參考官方 Kling 文件。
