  title: Pelias Geocoding Place Lookup API
  description: Pelias is a modular, open-source geocoding search engine built on Elasticsearch. It converts addresses and place names into geographic coordinates (forward geocoding) and geographic coordinates into places and addresses (reverse geocoding). Powered entirely by open data from OpenStreetMap, OpenAddresses, Who's on First, and Geonames, it is freely available under the MIT license and can be self-hosted or accessed via hosted services such as geocode.earth.

      description: Returns details for one or more places identified by their Pelias Global Identifier (gid). GIDs are returned in search/autocomplete/reverse results and should not be constructed manually. Note that GeoNames and Who's on First have stable IDs; OpenAddresses and OpenStreetMap IDs may change across data imports.
