  - name: No Hard Request Cap

      Additional calls were permitted and billed at $0.0001 per call rather
      than being rejected.

monitoring:
  description: >
    Usage could be monitored through the Dark Sky developer console at
    darksky.net/dev/console. Each API response also returned a
    X-Forecast-API-Calls header indicating the number of calls made today.
  header: X-Forecast-API-Calls

  The Dark Sky API was shut down on March 31, 2023. These limits are
  documented for historical reference. Apple WeatherKit is the successor API.
