Welcome to the UK Data Service open data Application Program Interface (API).

Our API exposes a set of read only calls to our open data sets upon which a developer can build an application. The API aims to make access to our data easier and to encourage users to create their own apps and visualisations to our data. All you need to get started is your own API Key which you can find out about here.
