BIS Effective Exchange Rates (Currency Strength) API

healthy 4,107 Subscribers

How strong each currency is on a trade-weighted basis, served live from the Bank for International Settlements' open statistics API — no key, nothing cached. An effective exchange rate (EER) measures a currency against a basket of its trading partners' currencies, not just one pair — it is the single best gauge of whether a currency is broadly strengthening or weakening. The BIS publishes nominal and real (inflation-adjusted) EER indices for 64 economies, against a broad (64-economy) or narrow (27-economy) basket, all on a base of 100. The rankings endpoint returns every economy's current EER index, ranked, so you can see the world's strongest and weakest currencies at a glance. The country endpoint returns one economy's EER index with its history and its 12-month change. The movers endpoint ranks the biggest currency gainers and losers over the past year — who has appreciated and who has depreciated most. Everything is the BIS's own compiled data, live, nothing stored; figures are monthly. This is the trade-weighted currency-strength layer for any forex, macro, trade or research app. Distinct from bilateral FX-rate and central-bank APIs — this is effective exchange rates: real and nominal trade-weighted currency strength, from the BIS. 3 endpoints, no key on our side.

BIS Central Bank Policy Rates API

The headline interest rate of every major central bank in the world, side by side, served live from the Bank for International Settlements' open statistics API — no key, nothing cached. The BIS compiles the official policy rate for around 40 monetary authorities — the Federal Reserve, the ECB, the Bank of England, the Bank of Japan and dozens more — onto one consistent monthly series. The policy-rates endpoint returns the current rate for every central bank in a single call, ranked from highest to lowest, so you can see the whole global rate landscape at a glance: in mid-2026 Türkiye near 37% at the top and the US Federal Reserve around 3.6%. The country endpoint returns one central bank's policy rate with its full history and its latest move. The changes endpoint compares each bank's two most recent readings and reports who has hiked, who has cut and who is on hold, with the size of the move — the global rate-cycle dashboard. Everything is the BIS's own compiled data, live, nothing stored; rates are monthly. This is the global monetary-policy layer for any macro, fixed-income, forex or research app. Distinct from single-central-bank APIs — this is every central bank's policy rate in one place, from the BIS. 3 endpoints, no key on our side.

Currency Strength API

A live currency strength meter as an API — it ranks 30+ major currencies by how much each has strengthened or weakened against the whole basket over a chosen period, computed from European Central Bank reference rates. Pull the full strength ranking, one currency's strength with its rank and per-pair changes, or any pair's cross-rate and period change. The classic dashboard forex traders watch, delivered as clean JSON. Distinct from raw exchange-rate and conversion APIs — this is the derived strength analytic.

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.
