Currency Exchange
Convert any amount between 32 fiat currencies (live European Central Bank rates) AND major cryptocurrencies (BTC, ETH, USDC, SOL, ICP, CELO and more, live Coinbase spot rates) — fiat↔fiat, crypto↔fiat, and crypto↔crypto all work; fiat codes outside the ECB set and long-tail tickers fall back to Coinbase/CoinGecko spot. Returns converted amount, exchange rate, inverse rate, rate date, and the rate source (ecb | coinbase | coingecko | same) so agents can price, invoice, and compare across fiat and crypto without a paid forex/crypto API. Historical dates apply to fiat pairs only.
Start with a quote-only recipe. Payment signing stays in your project.

EVIDENCE
Each record has an exact-route quote outcome. Unresolved templates and potentially mutating methods are labeled instead of being invoked without provider-specific test input. A quote is still separate from a settled paid call.
