市場與價格

利率

提供台灣市場利率快照資料,適合用於折現參數設定、宏觀條件對照與研究流程。

This documentation page is currently available in Chinese only; English versions are coming soon.
GET/v2/datasets/interest-rate-snapshot

Overview

利率 API 提供台灣市場利率快照資料,可作為估值折現、風險參數與宏觀條件分析的基礎輸入。

資料對應 canonical topic `interest_rate_snapshot`,對外路徑採 `/v2/datasets/interest-rate-snapshot`。

  • 設定折現率或資金成本參數。
  • 作為宏觀條件過濾器,搭配價格與財務資料做策略檢查。
  • 建立利率變動時間序列並觀察市場反應。

Coverage

InstrumentsStart yearUpdate timingIncludes delisted
Not yet available (coming)Not yet available (coming)Not yet available (coming)coming

Figures are measured from the DB; unlisted fields defer to docs coverage (coming) — we don't fabricate cell by cell.

Request

使用此 endpoint 時,建議以 as_of_date 查單日快照,或以 date_from/date_to 查歷史區間。若流程需要長期序列,建議先批次落地再下游使用。

Query Parameters

欄位型別Required說明
as_of_datestringno指定單一資料日期(YYYY-MM-DD)。
date_fromstringno查詢起始日期(YYYY-MM-DD)。
date_tostringno查詢結束日期(YYYY-MM-DD)。
limitintegerno回傳筆數限制。
offsetintegerno分頁偏移。

Response Shape

回應採 canonical envelope,頂層包含 query/meta,實際資料位於 envelope.data。

Field 說明

欄位路徑型別說明
datasetstring資料集識別,固定為 interest_rate_snapshot。
meta.rows_returnedinteger回傳資料筆數。
envelope.data[].as_of_datestring資料日期。
envelope.data[].policy_rate_pctnumber|null政策利率(百分比)。
envelope.data[].overnight_rate_pctnumber|null隔夜利率(百分比)。
envelope.data[].source_namestring|null來源識別(例如 cbc_official)。

Usage Notes / 使用建議

  • 此頁使用 data-api-standard 版型,與技術指標、估值資料、TWSE/TPEx 日線價格頁一致。
  • 若要做跨資料集分析,建議保留 as_of_date 以便和 index-data、market-breadth 對齊。
  • 資料可用範圍會依帳號方案與 API key 權限而定,實際以控制台顯示為準。

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.

Plan Requirement

  • Route:/v2/datasets/interest-rate-snapshot
  • 適用方案:實際可用範圍與配額以控制台方案顯示為準
