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.

Curation & Accuracy

This directory blends AI‑assisted discovery with human curation. Entries are reviewed, edited, and organized with the goal of expanding coverage and sharpening quality over time. Your feedback helps steer improvements (because no single human can capture everything all at once).

Details change. Pricing, features, and availability may be incomplete or out of date. Treat listings as a starting point and verify on the provider’s site before making decisions. If you spot an error or a gap, send a quick note and I’ll adjust.
