    twse_search_datasets搜尋臺灣證交所與期交所 OpenAPI 有哪些資料集可用。取資料前先用這個找 dataset_id。會比對資料集代號、中文說明與欄位名稱。期交所的資料集代號一律以 taifex/ 開頭，搜期貨與選擇權可用 tag="期貨與選擇權"。
    twse_describe_dataset查看某個資料集的完整欄位定義，取資料前用來確認要過濾／投影哪些欄位。
    twse_get_dataset取得證交所或期交所資料集內容，支援伺服器端過濾、欄位投影與分頁。兩邊的每個資料集都是一次回整份（可能上萬筆），務必用 code/match/fields 縮小範圍。
    twse_etf_snapshot一次取得單一上市 ETF 的完整概況：基本資料 + 前一交易日價量 + 定期定額熱度。價量為前一交易日，不是盤中即時；要當下價格請用 twse_realtime_quote。合併三個證交所資料集並行查詢。任何一段查不到都會標成 null 並記在 caveats，不會整個失敗。
    twse_realtime_quote取得盤中即時報價（約 5 秒更新一次）。OpenAPI 只有前一交易日資料，要當下的價格得走基本市況報導站。ETF 與上市股票用 market="tse"，上櫃用 "otc"。
