What This Skill Does
Converts between 150+ currencies using real-time exchange rates from exchangerate-api.com. Supports single conversions, base-currency rate tables, and listing all available currency codes. Rates update daily around 00:00 UTC.
No API key or account is required, unlike most exchange rate services that gate real-time data behind registration or paid tiers.
When to use it
- Converting USD to CNY before an overseas purchase
- Checking EUR rates before a trip to Europe
- Comparing JPY and KRW against USD in one table
- Calculating invoice amounts in a foreign currency
- Looking up the currency code for a less-common country
