How this service works
Search the national open data portal of Switzerland (opendata.swiss) 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
A JSON object containing: a list of up to 10 matching dataset items (each with id, title, last modified timestamp, source URL, publishing organization, and resource/file count), the search query used, total result count, the data source (opendata.swiss), country (Switzerland), licence information with URL, and the timestamp of when the data was fetched.
Example use cases
Swiss climate dataset discovery
“Search opendata.swiss for datasets related to climate change in Switzerland and list the titles, which organizations published them, when they were last updated, and how many files each has.”
Specific Swiss dataset lookup by ID
“Fetch the details for the dataset with the ID 'klima-planhinweiskarte-nacht' from Switzerland's open data portal — I need the title, publisher, last modified date, and official link.”
Swiss cantonal population data research
“Find datasets about population statistics from Swiss cantons on opendata.swiss — show me what's available, who published each one, and the link to the official dataset page.”
Technical details
Endpoint
GEThttps://api.maxwellinternational.ai/v1/gov/ch/open-data?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to discover or retrieve datasets from Switzerland's official national open data portal (opendata.swiss). Prefer it over generic web search when you need structured metadata (title, publisher, file count, last modified, official URL) about Swiss government open datasets. Choose the France equivalent endpoint for French open data, or EDGAR endpoints for US financial filings.
Side effects
- 404 response when a specific dataset ID does not exist (not charged)
- Empty results list when no datasets match the keyword
- Rate limiting or upstream portal unavailability causing delayed or failed responses
- Stale or missing modification dates when the portal does not provide them
- Licence information is top-level portal terms only; individual dataset licences must be checked on the official dataset page
