Narodowy Bank Polski (Poland) FX & Gold API

healthy 4,419 Subscribers

Live official Polish foreign-exchange and gold data, served straight from the National Bank of Poland's open API — no key, nothing cached. The rates endpoint returns the NBP daily fixing: the official mid rate of every world currency against the zloty (PLN), table A for the common currencies and table B for the exotic ones, with the bulletin number and date. The currency endpoint returns one currency's mid rate, its bid and ask from the trading table, and its recent history — the US dollar fixed at about 3.69 zloty in mid-2026. The bidask endpoint returns the full trading table (table C): every currency with its buy and sell rate and the spread between them. The gold endpoint returns the NBP accounting price of gold — one gram of pure gold in zloty — with recent history, around 509 zloty a gram. The convert endpoint turns an amount from any currency into any other, crossed through the zloty at the official fixing, so you can convert USD to EUR or JPY to PLN in one call. Everything is the central bank's own published data, live, nothing stored. This is the Polish zloty FX-and-gold layer for any forex, payments, e-commerce or treasury app operating in Poland and Central Europe. Distinct from the ECB, Fed, Bank of Canada, Norges Bank, Bank of England and Brazil central-bank APIs — this is the zloty, its bid/ask trading table and the NBP gold price. 6 endpoints, no key on our side.

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.

Chile Economy API

Live Chilean economic indicators from mindicador.cl (Banco Central de Chile data). Chile runs on indicators no other currency uses: the UF (Unidad de Fomento) is an inflation-indexed unit that prices mortgages, rents and contracts, and the UTM (Unidad Tributaria Mensual) is the tax unit — both quoted in pesos and updated daily. The feed also carries the observed dollar and euro, the IPC inflation index, the IMACEC activity index, the central bank policy rate (TPM), the copper price (Chile is the world's top copper exporter) and unemployment. The indicators endpoint returns every indicator's latest value; the indicator endpoint returns one with its recent series; the history endpoint returns a full year of daily values; the convert endpoint converts amounts between the peso, UF, UTM, dollar and euro. Read live, nothing stored. This is Chile's own UF/UTM, FX, rate and copper indicator layer — distinct from generic FX feeds.

Central Bank of Türkiye FX API

Live official exchange-rate data for the Turkish lira (TRY) from the Central Bank of the Republic of Türkiye (TCMB) — straight from its public daily rate XML as clean JSON. Unusually, the TCMB publishes four rates per currency: forex buying, forex selling, banknote buying and banknote selling. Get all of these for every published currency against the lira, for the latest or any past business day, normalised to one unit; pull a single currency's four rates, mid and the inverse; convert an amount between any two published currencies (including TRY) at the forex mid rate; or list the quoted currencies. Read live from the TCMB, nothing cached. This is the official Turkish-lira central-bank rate, with the forex/banknote split few other feeds expose — distinct from the ECB, BCRA, BCRP, NRB and other central-bank feeds and from market mid-rates: the TCMB's own lira rates.

Nepal Rastra Bank FX API

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.
