Overview
Official public sources first, so every Taiwan market row traces back to its source, its processing and the API response it came out of.
The left-hand navigation lists every dataset, and Quick Start walks through building a first request. For agents and internal tools that need to read the documentation programmatically, the OpenAPI spec, llms.txt and the MCP server are the entry points.
/public-first, treating TWSE, TPEx, MOPS and other official public data as the canonical source. What is claimed publicly today is a TWSE-first verified baseline.Market prices: TWSE daily prices are the verified primary path. TPEx daily prices are currently beta / limited, with historical depth still being filled in. Adjusted prices are not within what we claim as publicly available.
Financials and growth: monthly revenue, income statement, balance sheet and cash flow statement come primarily from MOPS, the Market Observation Post System. Valuation and financial metrics are derived by combining price, share capital, market capitalisation and reported financials.
Chips and capital flow: institutional trading and margin/short data take TWSE and TPEx official public data as the preferred source.
Companies and events: issuer profiles, company announcements, the event calendar, structured events, corporate actions and dividends come from TWSE, TPEx and MOPS official public information, standardised by the platform.
Classification and strategy layers: theme classification, index classification, features, factor-data, time-alignment and screener are layers the platform organises, maps or derives from official data.
