Connect TWSE (Taiwan Stock Exchange) to ChatGPT

This server connects your AI client to the Taiwan Stock Exchange's OpenAPI. Taiwan sits at the center of the global semiconductor supply chain, and its listed companies file a disclosure that exists almost nowhere else: monthly revenue, published around the 10th of the following month. TSMC's monthly number is watched worldwide as a real-time read on AI and chip demand.

Key features:

• list_companies: search TWSE-listed companies by Chinese/English name, 4-digit stock code (2330 = TSMC) or unified business number. The unified business number joins directly with Taiwan's GCIS company registry server.
• get_monthly_revenue: the latest monthly revenue with month-over-month, year-over-year and year-to-date changes, filterable by company or by industry (e.g. 半導體業, sorted by revenue) - so 'how did Taiwan's semiconductor sector do last month' is one call.
• get_quarterly_financials: the latest quarterly income statement (revenue, gross profit, operating income, net income, basic EPS) for general-industry companies.

Dates and fiscal years arrive in the ROC (Minguo) calendar; this server converts them to the Gregorian calendar so 11506 comes back as 2026-06. Amounts are in thousand New Taiwan Dollars.

No API key is needed. Pair with the OpenDART server (Korea) and SEC EDGAR (US) to cover the semiconductor disclosure triangle.
