Live interbank mid-market rates, 160+ currencies
The real exchange rate, refreshed every 60 seconds — what you show a customer or price a product in.
Loading live rate…Official central bank rates
The published figure an auditor or tax office expects — 105 central banks and tax authorities, by date.
Loading published rate…Official Central Bank & Tax Authority Rates
Mid-market rates are great for display — but tax filings, customs declarations, and audited invoices need the official published rate. We serve both from one API.
Reference rates from the Fed, ECB, Bank of England, Bank of Japan, and 98 more central banks — plus the compliance rates published by UK HMRC, the U.S. Treasury, and Swiss customs (BAZG) for VAT, customs, and financial reporting. History runs back to 2000 and earlier for major sources — the ECB series to 1999, the SNB monthly series to 1914 — so audits and restatements aren't capped at recent years.
Same key, same SDKs — every bank also ships as its own npm package.
One call — from your app or your AI agent
Localise every price for the visitor in front of you, and let an MCP client answer the same question in plain language. Both are live — pick a currency and the figures and the agent's reply update together.
