Frankfurter's foreign exchange rates, blended from what central banks and other official sources publish rather than taken from any one of them. Latest and historical daily rates, reaching back to 1999 for the currencies that go that far. getCurrencies says which currencies are covered and getProviders which sources are blended, so a caller that needs either asks rather than assuming.
