The OpenStreetMap TagFinder API is a RESTful HTTP API that provides users access to the underlying data on the OpenStreetMap wiki. Users can integrate TagFinder data in their webpage or application.
OpenStreetMap is a project which creates and distributes free geographic data for the world. Users have tagged things such as "points of interest". The most important tags are documented on the OpenStreetMap wiki, yet no true "tag search" exists. TagFinder is a web page where one can simply search for a term and get back a managable list of related tags. The most relevant information about tags is provided, as well as links to further details on the OpenStreetMap wiki and statistics at TagInfo.org.
