City, Nantes Open Data vs Open Government, ACT
Nantes Métropole's open-data portal runs OpenDataSoft; the stored record's `API Key` requirement is stale — a live keyless GET against the v2.1 Explore API (`data.nantesmetropole.fr/api/explore/v2.1/catalog/datasets`) returned full JSON catalogue metadata with a wildcard `Access-Control-Allow-Origin` header, and dataset exports in GeoJSON and CSV worked the same way with no key. An API key is only required for OpenDataSoft's write/administration endpoints, not for reading the catalogue's 590+ datasets.
Data.act.gov.au is the Australian Capital Territory's open-data portal, run on Socrata; its catalog discovery API at `www.data.act.gov.au/api/catalog/v1` answers keyless GETs with full dataset JSON and a wildcard `Access-Control-Allow-Origin` header (the bare `data.act.gov.au` apex briefly redirects through plain HTTP before landing back on the `www` host over HTTPS, so link to `www` directly). Individual datasets are queryable through Socrata's SODA API in JSON or CSV, covering ACT government services, planning, and community data.
