Cabbage is a currency converter.

mechanics

It just fetches exchange rates from ExchangeRate-API. Don’t use this if real-time conversion precision is necessary. The API response is cached and only refreshed when there’s an updated set of rates available to minimise unnecessary calls.

The URL hash contains the currency pair (ISO 4217) and monetary amount separated by hyphen-minus:

convert 100 THB to USD
