https://taiwan-business-day-live.wuryan529.workers.dev/fx/historyOverview
Exchange rate history: daily exchange rates between two currencies over the last 7-90 days (default 30), with the start and end rates, percentage change, high, low and average. Use it for 'USD to TWD exchange rate history', 'EUR to JPY trend this month', rate movement checks and volatility estimates. Rates are European Central Bank reference rates via Frankfurter; TWD comes via Frankfurter v2, as the ECB does not publish TWD.
