Nepal Rastra Bank FX API

healthy 3,871 Subscribers

Live official exchange-rate data for the Nepalese rupee (NPR) from Nepal Rastra Bank (NRB), the central bank of Nepal — straight from its public Foreign Exchange Rate API as clean JSON. Get the NRB's official buy and sell rate for every published currency against the rupee for the latest (or any past) day, normalised to one unit; pull a single currency's buy, sell and mid rate and the inverse; retrieve a currency's daily NRB buy/sell rate over a date range; convert an amount between any two quoted currencies (including NPR) at the NRB's mid rate; or list the NRB's quoted currencies. Read live from the NRB, nothing cached. Note the NRB quotes both a buy and a sell rate, and some currencies (such as the Indian rupee) are quoted per 100 units — every rate is also normalised to one unit for you. This is the official Nepalese-rupee central-bank rate — distinct from the ECB, BCRA, BCRP and other central-bank feeds and from market mid-rates: the NRB's own published rupee buy/sell rates.

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.

FX Carry Trade API

Live carry-trade and rollover analytics that FX traders run before borrowing a low-yield currency to buy a high-yield one, computed on demand from the interest rates you pass in — no key, no cache, nothing stored. The carry endpoint returns the interest-rate differential, the carry income over a holding period, the financing-adjusted yield and the leveraged return on margin, so you see exactly what a position earns. The rollover endpoint returns the daily, weekly and monthly swap — positive when you receive carry, negative when you pay it — the number a broker debits or credits each night. The breakeven endpoint returns how far the spot rate can move against the position before the carry is wiped out: the cushion the carry buys you, and the break-even spot level. This is an interest-rate and carry engine, distinct from pip and lot calculators and price tools: it turns two yields, leverage and time into the income and the risk cushion of a carry trade. The carry trade is one of the most-used FX strategies (think funding in yen to hold a higher-yielding currency), and these are the numbers behind it. Computed locally and deterministically, so it is instant and private. Ideal for FX dashboards, strategy back-tests, position sizers and trading tools. Rates are annual percentages (5.5 = 5.5%). Live, nothing stored. 3 compute endpoints. For live policy rates feed them in from a central-bank or rates API.
