  title: Geocode Earth API
  description: >-
    Hosted geocoding and address autocomplete API built on the open-source
    Pelias geocoder. Provides forward (search), autocomplete, reverse, and
    structured geocoding plus place lookup over open data sources
    (OpenStreetMap, OpenAddresses, Who's on First, and Geonames). All
    responses are GeoJSON FeatureCollections. Authentication is via an
    api_key query string parameter.
