Overview
The Poland Open Government Data API (dane.gov.pl) provides access to thousands of official datasets published by Polish public institutions, covering topics from transportation and demographics to environment and finance. No API key is needed, and the platform supports English-language search queries. It's built on CKAN, a widely used open data standard, so the API structure will be familiar to many developers.
Beginner Tip
Use the English version of the portal (dane.gov.pl/en) and its CKAN-compatible API to search datasets in English. Start with "package_search" to explore available data before deep-diving into specific datasets.
Available Data
The kind of data this API exposes, based on its documentation. We could not call the endpoint to confirm the exact field names.
Example Response
Illustrative shape only — we were not able to call this endpoint (it requires credentials or exposes no public sample URL), so the fields below show the kind of data this API returns rather than a recorded response.

"data": {
"result": "Data from Open Government, Poland",
"description": "Poland Government Open Data",
"timestamp": "2025-01-15T10:00:00Z"
}
} Field Reference

Implementation Example
Calls a real endpoint of this API. Replace any placeholder credentials with your own key.
const url = "https://dane.gov.pl/api/3/action/package_search?q=transport&rows=5";
const response = await fetch(url);
if (!response.ok) throw new Error(`Request failed: ${response.status}`);
const data = await response.json();
console.log(data); What Can You Build?
