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. Returns converted amount, exchange rate, inverse rate, rate date, and rate source so agents can price and invoice across fiat and crypto without a paid forex API.
