  what3words has divided the world into a grid of three-metre squares and
  given each one a unique three-word address (e.g. ///filled.count.soap). The
  what3words Public API converts between three-word addresses and latitude /
  longitude coordinates, offers an AutoSuggest with autocorrect for
  voice/typing input, exposes supported languages and locale variants, and
  returns grid sections as GeoJSON. The API is HTTPS GET only, authenticated
  by API key in a query parameter or X-Api-Key header, and is wrapped by
  official SDKs for Swift, Android, Java, JavaScript, Python, PHP, and .NET,
  plus UI components for map and OCR experiences.
