Euro Short-Term Rate (€STR) API
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.
