About this API

dane.gov.pl is the central government open-data catalog — it aggregates thousands of datasets published by ministries, central agencies, and local governments. Instead of manually searching dozens of individual institutions' sites, a single API lets you search them all at once.

Frequently asked questions

Do I need an API key?

No, the portal is fully public — no registration, no key.

What data does this API return?

Dataset metadata (title, description, institution, file format) and links to the resources themselves — from weather data to local-government budgets. The actual content depends on what each institution has published.

Can this API be called directly from a browser?

Yes — the API reflects the request's Origin header as an allowed CORS source, so it works straight from frontend code (hence the live "Try it" button above).

Who runs this API?

Poland's Chancellery of the Prime Minister. Full documentation is available at api.dane.gov.pl/doc.
