The rates endpoint returns the NBT's official rate for every published currency against the somoni, normalised to one unit; the rate endpoint returns a single currency's official rate (somoni-per-unit and the inverse); 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 TJS) at the NBT's official rates, cross-computed through the somoni. Live, no key, nothing stored. Distinct from the ECB, SNB, NBU, HNB, NBG, NBRB, CBU, CBAR, BOI, NBK, BNM and other central-bank feeds and from market mid-rates — this is the National Bank of Tajikistan's own official somoni exchange rate.",
