轉換預設

除了基礎轉換工具之外，SnapOtter 還提供 83 個專用的轉換預設端點。每個預設都會鎖定輸出格式並委派給其基礎處理管線，因此行為、驗證與輸出約定都會與下方所列的基礎工具相符。

API Endpoint Pattern

POST /api/v1/tools/<section>/<presetId>

傳送 multipart/form-data，其中包含一個 file 部分以及選填的 settings JSON 字串。預設會遵循基礎工具的回應約定。快速預設通常會回傳 200 並帶有 downloadUrl，但若超過同步等待視窗，則可能回傳 202。影片預設以及長時間執行的檔案／文件預設會回傳 202，並從 /api/v1/jobs/<jobId>/progress 進行進度串流。PDF 轉影像的預設會回傳各頁的下載 URL 以及一個 ZIP URL。

Notes

• 預設是一等的 API 端點，並且在其基礎路由支援批次處理的情況下，也可用於批次請求中。
• 使用影片轉換的預設可能會回傳 202 Accepted；請在下載結果前連接到工作進度的 SSE 端點。
• 若需要預設未提供的進階選項，請直接呼叫基礎轉換工具，並在 settings 中設定輸出格式。
