European Central Bank (ECB) Data Portal

EUR exchange rates, ECB policy rates and eurozone macro statistics.

The ECB SDMX 2.1 REST API provides access to EUR-based exchange rates against all IMF currencies (updated around 16:00 CET every trading day), ECB monetary-policy rates (MRO, MLF, DFR), EURIBOR, HICP inflation per EU country and more than 250 additional dataflows. Fully open, no authentication. The ECB is the authoritative source for EUR-based rates — Norges Bank uses the ECB rates as the basis for the official NOK rate.
