The National Archives Labs will be closing shortly. You can still access archived versions of the content at the UK Government Web Archive. The Valuation Office map finder will still be available.

Please contact Webmaster if you have any queries.

The National Archives’ API

Developers can explore our Discovery service using our new API (application programming interface).

The National Archives has designed a RESTful interface that allows developers to query the search engine and our Catalogue database within the Discovery service application programmatically, and returns results in XML for further processing.

The service is offered as a beta with some functionality still to be developed.  If you would like access to our API, please email us at, and please include the IP address from which you will be sending requests to our API.

Find out more about our API.

    I’d love to know if the API includes the Web Archive, but am interested in any case.
