National Bank of Georgia API
Live official exchange-rate data from the National Bank of Georgia (NBG), the central bank of Georgia, for the lari (GEL) — uniquely including each rate's daily change: the NBG official rate for every published currency (normalised to one unit) with the day's change, a single currency's lari-per-unit rate and inverse plus daily change, a currency's official rate on a specific past date, and currency conversion between any two published currencies (including GEL) cross-computed through the lari at NBG rates.
