Steps
Create/select a Google Cloud project, enable billing, enable the Air Quality API, and generate an API key in Cloud Console
Send POST https://airquality.googleapis.com/v1/currentConditions:lookup?key=YOUR_API_KEY with a JSON body containing location.latitude and location.longitude
Optionally add extraComputations (HEALTH_RECOMMENDATIONS, POLLUTANT_CONCENTRATION, LOCAL_AQI, POLLUTANT_ADDITIONAL_INFO) and languageCode
Read indexes[] for AQI values (default is Universal AQI 'uaqi'; request LOCAL_AQI for country indexes like 'usa_epa') and pollutants[] for concentrations
For a map overlay, fetch PNG tiles from GET https://airquality.googleapis.com/v1/mapTypes/{TYPE}/heatmapTiles/{Z}/{X}/{Y}?key=YOUR_API_KEY (e.g. TYPE=US_AQI)
Known gotchas
Requires a Google Cloud project with billing enabled — there is no standalone free-signup token flow; usage is billed/quota-managed via Cloud Console
Data is hourly-granularity, not minute-level real-time, and coverage/resolution varies by country
Heatmap tile X,Y coordinates must be valid for the requested zoom level (0-16) or the API errors; each tile is a fixed 256x256 PNG
