Usage Notes / 使用建議

  • 此頁為 productized endpoint,請勿與 legacy 回應格式混用。
  • 若要做事件整合分析,可搭配 `/v2/datasets/events` 與 `/v2/datasets/structured-events`。
  • 若需要較高頻價格對照,建議搭配 TWSE/TPEx 日線價格 endpoint。

Limitations & notes

  • Coverage is not the full market or full history; the actual range is defined by the coverage table above and the data_gaps in the response.
  • Missing data is flagged honestly — we don't fill gaps with estimated values.
  • The platform focuses on daily-frequency and fundamental data; it does not provide real-time quotes, intraday bars, or cryptocurrencies.
  • TWSE is the verified baseline; TPEx history depth and adjusted prices are currently beta / deferred, flagged per dataset.
  • Queries do not support an as_of parameter (roadmap). For point-in-time, filter on each row's knowledge_date, which is set conservatively to the statutory filing deadline. Daily prices do not carry that column.
