locationstringCity name or lat,lon coordinates (e.g. "London" or "51.5,-0.12")

latitudenumberLatitude coordinate (use instead of location for precise coordinates)

longitudenumberLongitude coordinate (use instead of location for precise coordinates)

Health Recommendations

Health recommendations combining AQI, UV, and pollen into a risk score (0-10) with guidance for exercise, walking, and ventilation. Optionally specify sensitive groups (asthma, COPD, allergies, children, elderly) for targeted advice.

Returns: Risk score, warnings, recommendations, activity guidance, and optional group-specific health advice

Parameters

locationstringCity name or lat,lon coordinates (e.g. "Sydney" or "-33.87,151.21")

latitudenumberLatitude coordinate (use instead of location for precise coordinates)

longitudenumberLongitude coordinate (use instead of location for precise coordinates)

sensitive_groupsarrayHealth conditions or groups to get targeted advice for (e.g. ["asthma", "allergies"])

Frequently Asked Questions

Can I check air quality for my city without coordinates?

Yes. `current_air_quality` accepts city names or lat/lon and returns AQI, pollutant levels, pollen counts, UV index, and advisories.

Can I see whether conditions will improve later this week?

`air_quality_forecast` gives up to 7 days of AQI and pollutant forecasts, and `pollen_forecast` adds pollen type breakdowns for allergy planning.

Can I get advice for asthma, allergies, or outdoor exercise?

`health_recommendations` combines AQI, UV, and pollen into a risk score with guidance for walking, exercise, and ventilation.

Can I find the nearest monitoring station?

`monitoring_stations` looks up nearby OpenAQ stations, including what they measure and how far away they are, where coverage exists.
