Converts an amount between any cryptocurrency and fiat currency pair, or between two cryptocurrencies, using real-time exchange rates sourced from CoinAPI. Supports all crypto-to-fiat (BTC/USD, ETH/EUR), fiat-to-crypto (USD/BTC), and cross-crypto (BTC/ETH) conversions. Use crypto_fx_rates when the conversion involves at least one cryptocurrency and a specific amount must be converted. Prefer crypto_price when only the spot price of a coin in fiat is needed without converting a specific amount, or prefer crypto_price_lite for the same spot price with a minimal response schema. Prefer currency_convert or currency_fx_lite when both currencies are fiat — those tools use ECB/Frankfurter or mid-market rates and do not consume a CoinAPI quota. Requires a CoinAPI key to be configured on the server.
