What is the data.europa.eu API?

The data.europa.eu API is a free, key-free search API over the official EU open data portal, covering more than 1.7 million datasets from EU institutions and every member state, with multilingual metadata.

This is the single aggregation point for European open data, federating national portals from all 27 member states alongside EU institutional data. The breadth is genuinely enormous.

Multilingual metadata is both the strength and the complication: titles and descriptions come as language-keyed objects rather than plain strings, so you must select a language rather than reading a single value.

Common errors and how to fix them

Title is an object, not a string

Metadata is multilingual.

Fix: Read title.en, falling back to another available language — there is no guaranteed English value.

Enormous result counts

1.7 million datasets are indexed.

Fix: Always filter by country, catalogue or format as well as the query.

Dead distribution links

Datasets are federated from national portals.

Fix: Link availability depends on the upstream publisher; handle failures.

data.europa.eu API — frequently asked questions

Is the EU open data API free?

Yes, free with no API key. Individual datasets carry their own licences, most of them open.

How many datasets are covered?

More than 1.7 million, federated from EU institutions and the national open data portals of all member states.

Why are titles objects instead of strings?

Metadata is multilingual, keyed by language code. Read title.en where available, but be prepared to fall back — not every dataset has an English title.

Can I filter to one country?

Yes, use countryData with a country code to restrict results to that member state's portal.
