As opposed to our subscriptions with fixed monthly cost, One Call API 3.0 has its own, separate subscription that has a variable cost, in proportion to your actual use of the API. Apart from additional functionality (47+ years of historical data are now available via this API), users can configure and limit their usage to ensure that they don’t make more request than expected.

Here are the types of data that are available:

  • Current weather and forecasts:and government weather alerts
    • minute forecast for 1 hour
    • hourly forecast for 48 hours
    • daily forecast for 8 days
  • Weather data for any timestamp for 47+ years historical archive and 4 days ahead forecast
