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.

Historical rates

Reference rates from the Fed, ECB, Bank of England, Bank of Japan, and 118 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.
