Google Maps Air Quality History Lookup

Use this endpoint when you need historical air quality data for a specific geographic location over a time range, such as trend analysis, retrospective health assessments, or environmental reporting. Prefer this over current conditions endpoints when past data is needed rather than real-time readings.
