Open Government, Switzerland
Opendata.swiss is Switzerland's national open-data portal, built on CKAN — its own handbook documents the base API URL as `https://ckan.opendata.swiss/api/3/action/`, callable via the standard CKAN action API (e.g. `package_search`) with no key required. Both `opendata.swiss` and `ckan.opendata.swiss` sit behind bot-detection middleware that returned HTTP 403 to every direct request from this environment, so the live `Access-Control-Allow-Origin` header could not be captured this run and `cors` is left `unknown` rather than guessed; per the site's own documentation the API itself is public and keyless.
