Colorado Information Marketplace
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.
