The rates endpoint returns the NBK's official rate for every published currency against the tenge, normalised to one unit, with the day's change and direction; the rate endpoint returns a single currency's official rate (tenge-per-unit and the inverse) plus the change; the history endpoint returns a currency's official rate on a specific past date; the convert endpoint converts an amount between any two published currencies (including KZT) at the NBK's official rates, cross-computed through the tenge. Live, no key, nothing stored. Distinct from the ECB, SNB, NBU, HNB, NBG, NBRB, CBU, CBAR, BOI and other central-bank feeds and from market mid-rates — this is the National Bank of Kazakhstan's own official tenge exchange rate with daily change and direction.",
