Live official exchange-rate data from the National Bank of the Republic of Belarus (NBRB), the central bank of Belarus, for the Belarusian rouble (BYN): the NBRB official rate for every published currency (normalised to one unit), a single currency's rouble-per-unit rate and inverse, the daily time series of a currency's official rate over a full date range, and currency conversion between any two published currencies (including BYN) cross-computed through the rouble at NBRB rates.

CBR Russia FX API

Live official exchange rates from the Central Bank of Russia (Bank of Russia) — the daily fixing the regulator publishes for the rouble (RUB) against 50+ currencies. Unlike euro- or dollar-based feeds, this is the rouble's own official reference board: every currency with the bank's nominal, the official RUB value, the previous-day value and the day-over-day change in absolute and percentage terms. Get the whole board with per-unit RUB values, one currency's official fixing in full, an official CBR cross rate between any two currencies via the rouble, or a ranking of the biggest daily gainers and losers against the rouble. Live, no key, nothing stored. Distinct from the ECB, SNB, Bank of Canada, Norges Bank, NBP, CNB and BCB feeds and from market mid-rates — this is the Central Bank of Russia's official rouble fixing with day-over-day deltas and official cross rates. Perfect for FX, treasury, accounting, remittance and analytics apps.

Currency Converter API

Live foreign-exchange conversion across 160+ world currencies — the plain, developer-friendly converter. Get the latest rates for any base currency, convert an amount between any two currencies, read the rate (and inverse) for a single pair, or list every supported currency. Rates are read live from an open exchange-rate source that aggregates a broad set of feeds and covers far more currencies than ECB-only data — including emerging-market and exotic currencies such as the Nigerian naira, Indian rupee or Vietnamese dong. This is the everyday convert / latest-rates utility a checkout, invoice, pricing page or travel app needs — distinct from the FX analytics APIs in the catalogue (historical date ranges, pip and position-size calculators, triangular-arbitrage path maths, currency indices), which compute on rates rather than simply converting them.

NBKR Kyrgyzstan FX API

Live official foreign-exchange reference rates from the National Bank of the Kyrgyz Republic (NBKR), read straight from the bank's published fixing — no key on the data, nothing cached, nothing stored. Get every currency the NBKR fixes against the Kyrgyzstani som (KGS) for the day, each normalized to a clean per-unit rate; look one currency up on its own; pull the separate weekly accounting rates (valid for seven days); or convert any amount between two listed currencies by crossing through the som. The som is the base and rates carry the NBKR fixing date. This is the Kyrgyzstan national-central-bank feed specifically — a distinct official source, separate from the other FX, central-bank and market APIs in the catalogue, so treasury, invoicing, payroll and accounting workflows that need the legally-referenced KGS rate can read it directly.

Currency Index API

Live currency-index maths that FX desks run to turn a set of exchange rates into a single index value, computed on demand from the rates you pass in — no key, no cache, nothing stored. The dxy endpoint computes the US Dollar Index (USDX) from its six component rates using the official ICE weights and formula — feed in EUR/USD, USD/JPY, GBP/USD, USD/CAD, USD/SEK and USD/CHF and get the index value the way the exchanges calculate it. The index endpoint builds an arbitrary weighted index from your own components: geometric (the standard for currency indices) or arithmetic, with a scaling constant and negative weights for inversely-quoted pairs. The basket endpoint computes a trade-weighted index normalised to 100, showing how a currency has moved against a basket from a set of reference rates — above 100 means it strengthened. This is an index-construction engine, distinct from published effective-exchange-rate feeds and strength meters: you supply the rates and weights and it returns the index, deterministically. Works for any custom basket. Computed locally, so it is instant and private. Ideal for FX dashboards, custom dollar/euro indices, back-tests and macro tools. Live, nothing stored. 3 compute endpoints. For published effective-exchange-rate data use a central-bank or BIS API.
