description: The UK Government API Catalogue (www.api.gov.uk) is a directory of central and local government APIs, maintained
  by the Central Digital and Data Office (CDDO) and the Data Standards Authority. It lists APIs from departments such as Companies
  House, DVLA, DWP, the Environment Agency and HMRC, grouped by organisation, with links to each API's own documentation.
  The catalogue is a static site generated from a CSV file (data/catalogue.csv) in the co-cddo/api-catalogue GitHub repository;
  entries are submitted through GitHub issues. Data is Crown copyright under the Open Government Licence v3.0; it publishes
  no API of its own.
