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?

A market rate is a moving target; the rate Central Bank of the Republic of China (Taiwan) publishes is a fixed, citable figure that stays put once printed — which is why invoicing, customs, audit evidence, and statutory accounting in Taiwan lean on it rather than on a live feed. Every response from this API carries the bank's own rate_date, and on days with no publication you get the most recent published table — the one compliance rules tell 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/{YYYY-MM-DD} — the table for any date (paid 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.
