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.

Poland Statistics API — oanor API marketplace

Poland Statistics API

Official Polish statistics from Statistics Poland (Główny Urząd Statystyczny, GUS) via its Local Data Bank (BDL) as a clean, keyless JSON API. Get the latest Polish consumer price index and inflation — the annual index where the previous year = 100, so a value above 100 is the inflation rate — fetch any BDL variable's national time-series by its id, search the bank's 170,000+ variables by name, and browse the subject tree (prices, labour, population, national accounts, industry, trade and far more). A thin gateway over the GUS BDL REST API: you supply a variable id and how many recent years you want, we return tidy year/value observations. Ideal for inflation trackers, Polish and Central-European macro research and economic dashboards.

 Warsaw Stock Exchange (GPW) API — oanor API marketplace

Warsaw Stock Exchange (GPW) API

Live data for the Warsaw Stock Exchange (GPW, the Polish market) with no key: the live quote for one or more stocks by ticker (price, change, open/high/low, volume, market cap, P/E, sector, in zloty, with the company name), a ranked market screener (top gainers, losers, most active, or largest by market cap; primary Polish listings only), and the live value of the Warsaw indices (WIG, WIG20, WIG30).

 Bank Negara Malaysia FX & Rates API — oanor API marketplace

Bank Negara Malaysia FX & Rates API

Official central-bank data from Bank Negara Malaysia (BNM), the central bank of Malaysia, all quoted around the Malaysian Ringgit (MYR). Read every BNM foreign-exchange reference rate with its buying, selling and middle quote — each row carries the BNM quoting unit (the Japanese Yen, for example, is quoted per 100) plus a normalized myr_per_unit, so conversions are never ambiguous — look up a single currency, or convert any amount between two quoted currencies or MYR using the central-bank cross rate. Beyond FX, the same surface exposes the Kijang Emas gold bullion coin buying and selling prices (one, half and quarter ounce), the current Overnight Policy Rate set by the Monetary Policy Committee, and the published base rate, base lending rate and indicative effective lending rate for every licensed Malaysian bank. Rates always resolve to the latest published business-day fixing. Distinct from our other central-bank FX feeds: this bundles Malaysian FX, gold and policy/lending rates in one API.

 Central Bank of Myanmar FX API — oanor API marketplace

Central Bank of Myanmar FX API

Official daily foreign-exchange reference rates published by the Central Bank of Myanmar (CBM), quoted against the Myanmar Kyat (MMK). Read every CBM reference rate in one call, look up a single currency, or convert any amount between two quoted currencies (or MMK) using the central-bank cross rate. CBM follows a per-100 quoting convention for its low-value currencies — Indonesian Rupiah, Japanese Yen, Cambodian Riel, South Korean Won, Lao Kip and Vietnamese Dong are published per 100 units while every other currency is per 1 — so each rate carries both the raw quoted_rate and quoted_per plus a normalized mmk_per_unit, making conversions unambiguous. Rates always resolve to the latest published business-day fixing. Distinct from our other central-bank feeds (Bosnia, North Macedonia, Romania, Moldova, Nepal): this surfaces the Myanmar Kyat reference table specifically.
