How this service works

Search the national open data portal of Czechia (data.gov.cz) by keyword, or fetch one dataset by id: title, publishing organization, last modified date where the portal gives one, number of files and the official link, under the portal's licence terms (a dataset's own licence is on its official page). Uncached: 404, not charged, fetched within about a minute.

Output

Returns a JSON object with ok status, a list of dataset items each containing an ID, title, last modified date (if available), source URL, publishing organization name, and resource file count, plus overall total count, the query used, data source attribution, licence information, and fetch timestamp.

Example use cases

Discovering Czech environmental datasets

“Can you search data.gov.cz for open datasets related to air pollution and tell me who publishes them, how many files each has, and where I can find them?”

Fetching a specific Czech dataset by ID

“Fetch the details for dataset ID 00020699/a6dd7826d86120a6ecf42a902fa82aca from the Czech open data portal — I need the title, organization, and official link.”

Researching Czech demographic open data

“Search the Czech national open data portal for datasets about population statistics — give me the titles, publishers, and last modified dates for whatever comes up.”

Technical details

Endpoint

GEThttps://api.maxwellinternational.ai/v1/gov/cz/open-data?utm_source=zero.xyz

When to prefer

Use this endpoint when you need to discover or retrieve metadata for publicly available Czech government datasets from data.gov.cz. Prefer this over generic web search when you want structured, machine-readable dataset metadata including publisher, file counts, and direct portal links. Use the sibling Austria, Germany, EU, or UK endpoints for those respective portals.

Side effects

404 response when no cached result exists (not charged); fresh fetch takes up to one minute
Empty result set if no datasets match the keyword
Dataset ID not found returns an error or empty response
Portal temporarily unavailable causing fetch failure
Query timeout if data.gov.cz is slow to respond
