Data.parliament.uk vs District of Columbia Open Data
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.
Open Data DC is the District of Columbia government's catalogue of public datasets, spanning crime incidents, GIS/mapping layers, and financial and demographic data, published on an Esri ArcGIS Hub site. Datasets are queryable keyless through the Hub's search and DCAT feed APIs and through individual ArcGIS Feature/Map Services, returning JSON, GeoJSON, CSV, or shapefile depending on the layer. No account or API key is required to read data.
