Currency ExchangeGET /currency-exchange/convert · x402 API by netintel
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.
