Deutsche Bundesbank — System of indicators of the German residential property market (BBDY1)
This dataset provides the System of Indicators of the German Residential Property Market (BBDY1), an official time series collection published by the Deutsche Bundesbank via its SDMX 2.1 REST API. Data are accessible in XML (SDMX-ML), CSV, or JSON formats through a single endpoint, with queries constructed using a key path together with startPeriod, endPeriod, and lastNObservations filters to extract specific series. The dataset covers national indicators of residential property prices and market developments in Germany, and is freely accessible without authentication, supporting economic and housing-market analysis.System of indicators of the German residential property market (BBDY1) — official time series from the Deutsche Bundesbank, published as the BBDY1 dataflow over SDMX 2.1 REST. One endpoint serves XML (SDMX-ML), CSV (?format=csv) and JSON (?format=json); extract exactly the series you need with a key path and startPeriod / endPeriod / lastNObservations filters.
