ECB / Key interest rates (deposit facility, main refinancing, marginal lending)

The ECB's three policy rates, in percent, one observation per change date: DFR deposit facility rate, MRR_FR main refinancing operations fixed rate, MLFR marginal lending facility rate (MRR_MBR is the old minimum bid rate). Default: the last 10 changes. Answer is SDMX-JSON: dataSets[0].series maps a series key (dimension positions joined by :) to observations {"": [value]}; structure.dimensions.series and structure.dimensions.observation give the codes and the dates for each position.
