Central Bank of the Republic of China (Taiwan) Exchange Rates API — taiwan-central-bank-exchange-rate
Official Central Bank of the Republic of China (Taiwan) (Taiwan) daily exchange rates for Node.js and TypeScript. The published central bank rates behind tax filings, customs valuations, audits, and compliant invoicing — not market estimates, but the numbers Central Bank of the Republic of China (Taiwan) itself prints, every business day.
🚀 Why this client?
- 🏛️ Official rates — Central Bank of the Republic of China (Taiwan)'s own table, with the publisher's own
rate_date on every response
- 📅 History back to 2008 — point-in-time tables and daily series for any past date
- 🔀 Official vs derived, always flagged — computed inverse/cross pairs carry
derived: true, never mixed with official prints
- ⚡ Zero dependencies — pure ESM + CJS over global
fetch; Node 18+, Bun, Deno, and edge runtimes
- 🔷 Type-safe — full TypeScript definitions shipped with the package
- 🧾 Compliance-grade metadata —
rate_type, publication date, and source disclaimer on every response
Official rate, not mid-market: every value here is a number Central Bank of the Republic of China (Taiwan) itself published, fixed once printed and carrying the central bank's own rate_date — what filings and audits require. Need the live mid-market rate for pricing or display instead? Use the mid-market API or @allratestoday/sdk. The two can diverge by several percent.

📈 Latest official table
The image is rendered live from the keyless endpoint, so it follows the central bank's publications on npm and on GitHub alike without a new release. The same table as text is folded below for search and copy-paste: on GitHub a daily Action refreshes it whenever the central bank publishes a new table; on npm it is as of the package's publish date.
| Base | Quote | Type | Rate |
|---|
| USD | TWD | close | 32.838 |
Source: Official rates published by CBC, served by AllRatesToday. Rates are as printed by the central bank; AllRatesToday is not affiliated with it.
