  title: Placekey API
  description: >-
    The Placekey API resolves an address, point-of-interest, or
    latitude/longitude coordinate pair into a Placekey - a free, universal
    identifier for any physical place. It supports single lookups (POST
    /placekey) and bulk lookups of up to 100 queries per request (POST
    /placekeys). Authentication is via the apikey request header.
