Open Government, Poland API

Government / No Auth Required Beginner HTTPS CORS
Free to Use Varies (check documentation)

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.

Common Errors & Troubleshooting

Dataset title returns Polish-only content Some datasets only have Polish metadata with no English translation.
Use the web portal to preview dataset contents, or use translation tools to interpret Polish field names.
500 Internal Server Error Malformed query parameters or unsupported CKAN action.
Validate your query parameters and refer to the CKAN v3 API documentation for supported actions.
Resource download fails Some linked files are hosted on external government servers that may be unavailable.
Check the "url" field of the resource object and try accessing it directly in a browser first.
