Live euro short-term rate (€STR) data from the European Central Bank. The €STR is the euro area's overnight risk-free benchmark, computed daily by the ECB from the real unsecured borrowing of euro-area banks; it underpins euro derivatives and floating-rate contracts and is the successor to EONIA and a key reference alongside EURIBOR. The estr endpoint returns the latest rate plus its full daily statistics — the underlying borrowing volume, the number of reporting banks and transactions, the 25th and 75th rate percentiles and the share of the five largest banks. The policy endpoint returns the ECB key-rate corridor (deposit facility, main refinancing operations, marginal lending) and where €STR sits inside it. The history endpoint returns the €STR rate over recent days. Read live from the ECB, nothing stored. This is the euro overnight risk-free rate and ECB policy corridor — distinct from FX reference feeds, bond yield curves and money-market futures.

Live official exchange-rate data from the Croatian National Bank (Hrvatska narodna banka, HNB), the central bank of Croatia, against the euro — uniquely with three rates per currency (buying, selling and middle): the official rate for every published currency, a single currency's buying/selling/middle rate plus the inverse, a currency's official rate on a specific past date, and currency conversion between any two published currencies (including the euro) cross-computed through the euro at HNB middle rates.

Live official euro-area monetary data from the ECB Data Portal — no key, nothing cached. This is the money side of the euro, not exchange rates. The key-rates endpoint returns the ECB's three policy interest rates — the deposit facility rate, the main refinancing operations (MRO) rate and the marginal lending facility rate — the rates that set the price of money across the euro area, each with the date it took effect and recent history (deposit facility around 2.00%, MRO 2.15%). The estr endpoint returns €STR, the euro short-term rate, the overnight benchmark that replaced EONIA, with its recent path. The yield-curve endpoint returns the euro-area AAA-rated government bond spot-rate curve across maturities from 3 months to 30 years, with the 10-year-minus-1-year slope. Everything is the ECB's own published series. This is the euro-rates layer for any fixed-income, macro, forex or research app that needs authoritative European central-bank numbers. Live from the ECB, nothing stored. Distinct from exchange-rate APIs and from the Bank of Canada and US-Treasury APIs — this is the ECB's policy rates, €STR and euro yield curve. 4 endpoints.
