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.
