Returns the most recent foreign-exchange reference rates for a base currency against a set of target currencies, optionally scaled by an amount so the response is a direct conversion.
Rates are published once per working day from European Central Bank reference data, so intraday and weekend values repeat the most recent publication. Omit symbols to return every available currency.
Base currency, ISO 4217 code (e.g. USD). Defaults to EUR.
Amount of the base currency to convert. Defaults to 1.
Comma-separated target currencies, ISO 4217 (e.g. "EUR,GBP,JPY"). Omit for all.
