European Central Bank — Derived Data (DD)
Derived Data (DD) is an official time series dataset published by the European Central Bank through its Data Portal, distributed as the DD dataflow over the SDMX 2.1 REST API. A single endpoint provides data in XML (SDMX-ML), CSV, and JSON formats, allowing users to extract specific series using a key path along with startPeriod, endPeriod, and lastNObservations filters. The same series can also be browsed and charted interactively on the ECB Data Portal, making the dataset useful for economic and financial analysis across the euro area.Derived Data (DD) — official time series from the European Central Bank Data Portal, published as the DD dataflow over SDMX 2.1 REST.
