About Central Bank of the Republic of China (Taiwan)

Taiwan's central bank publishes exactly one exchange-rate series of its own: the NTD/USD interbank spot closing rate, sourced from Taipei Forex Inc. Multi-currency boards seen in Taiwan are commercial bank rates, not central bank publications. The official series is released each business afternoon and reaches back to 2008 in the bank's open data.

Why use the official Central Bank of the Republic of China (Taiwan) rate?

Live market rates move continuously, but tax filings, customs declarations, audits, and statutory accounting in Taiwan and beyond typically require the official rate published by Central Bank of the Republic of China (Taiwan) for a given date — a fixed, citable number that never changes after publication. This API serves those published tables with the bank's own rate_date on every response; weekends and holidays return the most recent published date, which is the rate compliance rules require you to apply.

Pairs the bank doesn't print directly are resolved from its table (inverse or cross via TWD) and explicitly flagged "derived": true — so what the bank printed and what was computed are never confused.

Endpoints

• GET /api/v1/central-bank/cbc/latest — latest table or single pair (all plans)

• GET /api/v1/central-bank/cbc/history — time series, up to 5,000 rows (paid plans)
• GET /api/v1/central-bank/cbc/availability — publication calendar: the dates the bank actually published (all plans)

Full parameter reference in the API documentation. Every request counts toward your plan's monthly quota — rates change once per business day, so caching a published table locally makes a small quota go far.
