City, Nantes Open Data vs Data.parliament.uk

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.

The Dataset Explorer's underlying Linked Data API, hosted at `lda.data.parliament.uk`, is still live: a keyless GET against `bills.json` returned real, paginated bill records (2,000+ results) with a wildcard `Access-Control-Allow-Origin` header, and `endpoints.json` lists dozens of other datasets (committees, attendance, members) served the same way. It's a legacy platform, though — Parliament now also runs newer per-domain REST APIs (`members-api.parliament.uk`, `bills-api.parliament.uk`) that cover the same ground with a modern interface and are worth checking first for new integrations.
