CKAN API Notes
Developers can access the data catalogue with the metadata API, as an alternative to the data.gov.uk web interface. The API provides both RESTful and functional interfaces, all in JSON format, making it suitable for a wide range of clients.
The base URL for the API is: https://data.gov.uk/api
The API is provided by the CKAN software and full instructions are provided here: http://docs.ckan.org/en/release-v2.2.3/api.html.
