OSM Tag Key Values and Usage Counts (Taginfo)

osmtaginfo/key-values

Lists the values used for one OpenStreetMap tag key (for example amenity, highway or cuisine), each with its number of uses, its share of the key's uses, whether it is documented on the OSM wiki and its wiki description. Sorted by usage count (most used first) or alphabetically, paged 1 to 50 values at a time; the total number of values is reported. Statistics are rebuilt from the OSM database about once a day. Data from OpenStreetMap contributors (ODbL), via OSM Taginfo; served by Eden Engine; not an official OpenStreetMap product.
