About this rate

Automatic mode uses Frankfurter first and falls back to ExchangeRate-API if the primary source is unavailable. Neither public endpoint needs an API key in AmpCub.

Your amount is never sent to the rate API. Only the selected currency pair is requested.
Frankfurter rates are cached for 10 minutes; the daily fallback is cached for 60 minutes to reduce rate-limit risk. Use Refresh rate to bypass the cache.
Frankfurter follows official-source publication schedules. The open fallback updates once per day and is rate limited. Neither is a tick-by-tick trading feed.
The converted amount is also written out in words, rounded to at most two decimal places for readability.

Reference rate only. Actual card, cash, remittance, or bank exchange rates may include spreads and fees.

Supported currencies and limitations

The selector includes common currencies such as TWD, USD, JPY, EUR, GBP, CNY, HKD, KRW, SGD and THB. Automatic mode tries two independent public endpoints. If neither can provide a valid rate, the page shows an error instead of inventing or reusing a hardcoded rate. Amount-in-words is intended for readability, not accounting or legal documents.
