About this API
The European Central Bank publishes, via an SDMX 2.1 RESTful web service, the full range of its statistical data — from reference euro exchange rates (the same ones shown on the ECB's site every business day) to monetary-policy interest rates, inflation indicators, and euro area monetary aggregates.
Frequently asked questions
Do I need an API key?
No, the service is fully public and free — no registration, no key.
What data does this API return?
Reference euro exchange rates against other currencies, ECB interest rates, inflation indicators (HICP), and a range of other euro area monetary and financial aggregates, current and historical.
Can this API be called directly from a browser?
No — the service doesn't return CORS headers, so a direct call from frontend code will be blocked by the browser. It needs to be called from a backend or other server-side environment.
Who runs this API?
The European Central Bank. Full documentation is available at data.ecb.europa.eu/help/api/overview.
