Open Government, Czech Republic API

Free to Use Varies (check documentation)

Overview

The Open Government Czech Republic API provides free access to official Czech government datasets published under open licenses, covering areas like public administration, transport, environment, and statistics. No API key is required. The English-language interface at data.gov.cz makes it accessible to international developers.

💡

Beginner Tip

The Czech open data portal uses SPARQL and DCAT standards in addition to a standard web interface; for beginners, the CKAN-compatible REST API at https://data.gov.cz/api/3/action/package_list is the easiest entry point.

Common Errors & Troubleshooting

Czech-language results Most dataset metadata is in Czech even on the English portal.
Use Czech keywords such as doprava (transport), zdravi (health), or ekonomika (economy) for better search results.
SPARQL endpoint errors Malformed SPARQL queries cause 400 errors on the semantic endpoint.
Start with the simpler REST API endpoints before attempting SPARQL queries; validate queries in a SPARQL editor first.
Dataset license restrictions Not all datasets are fully open; some have specific Czech legal conditions.
Always check the license field in the dataset metadata before using data in commercial or redistributed projects.
