City, Helsinki
Helsinki Region Infoshare (HRI) — the joint open-data service for Helsinki, Espoo, Vantaa, and Kauniainen — runs CKAN under the `/data` path rather than at the domain root. A live keyless GET against `hri.fi/data/api/3/action/status_show` returned full JSON with no `Access-Control-Allow-Origin` header on either a plain GET or an OPTIONS preflight, so browser-side cross-origin reads are blocked. Resources span the four-municipality region across transit, geospatial (WMS/WFS), and statistical datasets in CSV, XLSX, and shapefile formats.
