🌍 OpenAQ Air Quality Scraper

🚀 Map air quality monitors anywhere in seconds. One query around London returns 100+ stations with live PM2.5, PM10, NO2, and ozone readings.

🕒 Last updated: 2026-06-02 · 📊 22 fields per station · coordinate or country queries · live pollutant readings

Pull air quality monitoring stations and their latest measurements from the OpenAQ global network. Search by coordinates with a radius or by country code, and for every station get its location, provider, the pollutants it tracks, and the most recent readings for PM2.5, PM10, ozone, NO2, SO2, and CO with timestamps.

Coverage: the worldwide OpenAQ network of government and research monitors. Pass coordinates (for example "34.0522,-118.2437") with a radius, or a two-letter country code.

📋 What the OpenAQ Air Quality Scraper does

• Finds monitoring stations near coordinates or within a country.
• Returns 22 structured fields per station, including a full measurements list.
• Joins each sensor to its pollutant, value, units, and timestamp.
• Flattens PM2.5 and PM10 to top-level columns for quick comparison.
• Optionally filters to stations that measure a chosen pollutant.
• Exports to CSV, Excel, JSON, XML, or via API.

⚙️ Input

Example 1: by coordinates

{
"coordinates":"34.0522,-118.2437",
"radiusKm":15,
"maxItems":50
}

Example 2: by country, only PM2.5 stations

{
"countryCode":"GB",
"parameter":"pm25",
"maxItems":100
}

⚠️ Good to Know: OpenAQ requires a free API key. A shared key ships by default, but for heavy use get your own at explore.openaq.org. Some stations are historical, so check datetimeLast for the freshness of each reading. Coordinate queries surface the most active stations.

❓ Frequently Asked Questions

1. Do I need an API key? OpenAQ requires a free key. A shared key ships by default, and you can add your own for heavy use.

2. How do I search a city? Pass coordinates as "lat,lon" with a radiusKm. Coordinate queries surface the most active stations.

3. Can I search a whole country? Yes. Use countryCode with a two-letter ISO code.

4. What pollutants are covered? PM2.5, PM10, ozone, NO2, SO2, CO, and more, depending on each station.

5. Why is PM2.5 sometimes null? That station does not measure PM2.5. Check the parameters and measurements fields.

6. How fresh is the data? Each station shows datetimeLast. Some stations are historical, so this field reveals freshness.

7. Can I filter by pollutant? Yes. Set parameter to keep only stations measuring it.

8. What export formats are supported? CSV, Excel, JSON, XML, and API.

9. Can I run it on a schedule? Yes, with Apify Schedules and integrations.

10. Is there a free option? Yes. Free runs are limited to 10 items as a preview. Paid plans unlock up to 1,000,000.

🔌 Integrate with any app
