From the live rate to the yearly average for your books
Every endpoint shares the same API key, base currency handling and quota, so you never stitch together several providers for rates, history and reporting figures.
Start with the exchange rate API for live rates, the currency converter API for amounts, or the historical exchange rates API for any day since 1999.
GET /v3/latest170+ fiat, crypto and metal rates, updated up to every 60 seconds, and /v3/convert for any amount.
GET /v3/historicalEnd-of-day rates for any date back to 1999.
GET /v3/rangeDaily, hourly or minute series, plus month-end and week-end series over decades. JSON or CSV.
GET /v3/fluctuation
NewHow much every currency moved between two dates, in absolute terms and in percent.
GET /v3/average
NewAverage, low and high per month, quarter or year, the figures IFRS and US GAAP reporting uses.
GET /v3/officialThe official rates of 35 central banks such as the ECB, Fed and Bank of England, with full history.
