## Tools (2)

- `convert_currency`: Convert an amount from one currency to another using real, current
ECB reference exchange rates. Use for any "how much is X in Y"
question -- "convert 100 USD to EUR", "what's 50 GBP in yen".
`from_currency`/`to_currency` are 3-letter ISO codes (USD, EUR, GBP,
JPY, ...). Returns the converted amount, the rate used, and the date
the rate is from.
- `get_exchange_rate`: Look up today's exchange rate between two currencies, without
converting a specific amount. Use for "what's the exchange rate
between USD and EUR" style questions. `from_currency`/`to_currency`
are 3-letter ISO codes. Returns the rate and the date it's from.
