Envirofacts has developed a RESTful data service API to all of its internal data holdings. This functionality provides a user of Envirofacts with the ability to query any table through the use of a URL. The default output is in XML, which can be utilized in other applications, as well as tools such as Microsoft Excel or Access. Output options of JavaScript Object Notation (JSON), CSV, and Excel can be requested in the URL. The entire Envirofacts database metadata is available online, so that all tables and columns within Envirofacts are documented. Having the table structures available in this manner makes most of Envirofacts data easily available through the service. Additional information on how to use the RESTful data service API can be found on the Envirofacts RESTful data service API documentation page.
