ECB Data Portal

data.ecb.europa.eu

Official ECB gateway for euro‑area statistics with an open SDMX 2.1 REST API. The new endpoint is https://data-api.ecb.europa.eu/service/ (replacing the legacy SDW path). Content negotiation supports SDMX‑JSON, CSV, and SDMX‑ML. Charts and tables can be downloaded as CSV/XLS (long & wide), and charts as PNG/PDF/PPT. Typical update cadence is daily to monthly (e.g., reference FX rates around 16:00 CET on working days). ECB advises migrating from the old SDW URL as automatic redirects are planned to end on 1 Oct 2025.
