Colorado Information Marketplace vs Data.parliament.uk

The Colorado Information Marketplace is the state's open-data portal, built on the Socrata platform and covering budget, transportation, public-safety, and demographic datasets from Colorado agencies. Every dataset is queryable through Socrata's SODA REST API without an account, with an optional free app token only needed to raise the anonymous rate limit. Results are returned as JSON by default, with CSV and XML also available per dataset.

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.
