Official time series for EONIA (Euro OverNight Index Average / Euro Interbank Offered Rate), published by the European Central Bank as the EON dataflow through the ECB Data Portal's SDMX 2.1 REST API. A single endpoint serves data in XML (SDMX-ML), CSV, and JSON formats, allowing users to extract specific series using key paths and filters such as startPeriod, endPeriod, and lastNObservations. The same series can also be browsed and charted interactively on the ECB Data Portal website, providing euro-area money market reference rate data for economic and financial analysis.EONIA: Euro Interbank Offered Rate (EON) — official time series from the European Central Bank Data Portal, published as the EON dataflow over SDMX 2.1 REST.
