Gazetteer API

Resolve free-text place names to structured geographic regions — in milliseconds.

What is Gazetteer?

Gazetteer takes a list of free-text place names and returns the most specific common geographic region that contains all of them, using fuzzy matching and a hierarchical place database.

["Cuiabá", "Sinop"]          →  Mato Grosso (state)
["Paris", "Lyon"]             →  France (country)
["NYC", "LA", "Chicago"]      →  United States (country)
