  Weather Underground provides free API access to registered Personal Weather
  Station (PWS) contributors. The PWS API key is issued at no cost to station
  owners who upload data to the Weather Underground network. There are no paid
  tiers or packages; access is contingent on owning and actively contributing
  data from a registered PWS.
