Questions about official rates

What are official exchange rates?

They are the rates a central bank (or an official fixing authority) publishes itself, usually once per business day. Tax, accounting and customs rules often require a specific one, for example the ECB reference rates in the euro area or the NBP rates in Poland.

How are these different from market rates?

Market rates move continuously and differ between data providers. An official rate is a single published figure per day, so everyone who cites it gets the same number.

How current are the rates?

Every bank is checked hourly and a new publication appears within the hour after the bank releases it. The Federal Reserve publishes its H.10 rates weekly, so its newest rate can be up to a week old.

Can I get this data programmatically?

Yes. The currencyapi /v3/official endpoint returns any bank's rates for any date since its history starts, as JSON or CSV, and /v3/official/range returns whole date ranges.
