The official exchange rates API — 80+ central banks and tax authorities, 150+ currencies

Global Exchange Rates is a single, unified API for the official exchange rates published by more than 80 central banks and tax authorities worldwide — the rates that count for accounting, VAT, customs, and audit. One integration, 150+ currencies.

Official rates, not market estimates

Every rate is the official figure published by a central bank or tax authority — ideal for accounting, finance, ERP, tax, and reporting, anywhere a defensible, auditable rate is required. Download historical rates for most institutions, plus a proprietary daily "GLOBAL" blended rate.
