API - Air Quality Programmatic APIs

Share: aqicn.org/api/cn/

Initial setup

The first step is to make sure to acquire your own token for all API access.
You can get your token from the data-platform token page.

Map tile API

The map tile API can be used to show the real-time Air Quality index on a google, bing or openstreet map.
Read more about the Map tile API description and examples

Widget API

The widget API can be used to integrate the real-time Air Quality index on any web page.
Read more about the Widget API description


There is also a non-progammatic API for an easy integration with word-press, which can generate any of the widget below. For more information, go to your city page (eg aqicn.org/city/auckland), scroll-down until you find the "Download the real-time Air Quality Index Widget" and click on the "Wordpress & Blogger" logo.

JSON API

 $ curl -i "http://api.waqi.info/feed/shanghai/?token=demo"
The JSON API can be used for advanced programmatic integration:
  • Access to more than 9000 station level and 600 city level data
  • Geo-location query (based on latitude/longitude or IP address)
  • Individual AQI for all pollutants (PM2.5, PM10, NO2, CO, SO2, Ozone)
  • Station name and coordinates
  • Originating EPA name and link
  • Current weather conditions
  • Stations within a map lat/lng bounds
  • Search stations by name
For more information, you can use the on-line API documentation or refer to the sample javascript code / web demo.

Note that more functionality will be added during the coming weeks:
  • Air Quality forecast (for 3~8 days)
  • Weather forecast (for 8 days)
  • World ranking and trend
  • Neighbor stations AQI
  • Historical Data
  • Pollutant raw concentration (for usage with different scales)
  • PubSub notification service

    关于空气质量与空气污染指数

    本网站采用的污染指数和颜色与EPA是完全相同的。 EPA的指数可以从 AirNow上查到

    空气质量指数 空气质量指数级别（状况）及表示颜色 对健康影响情况 建议采取的措施
    0 - 50 一级（优） 空气质量令人满意，基本无空气污染 各类人群可正常活动
    51 -100 二级（良） 空气质量可接受，但某些污染物可能对极少数异常敏感人群健康有较弱影响 极少数异常敏感人群应减少户外活动
    101-150 三级（轻度污染） 易感人群症状有轻度加剧，健康人群出现刺激症状 儿童、老年人及心脏病、呼吸系统疾病患者应减少长时间、高强度的户外锻炼
    151-200 四级（中度污染） 进一步加剧易感人群症状，可能对健康人群心脏、呼吸系统有影响 儿童、老年人及心脏病、呼吸系统疾病患者避免长时间、高强度的户外锻炼，一般人群适量减少户外运动
    201-300 五级（重度污染） 心脏病和肺病患者症状显著加剧，运动耐受力降低，健康人群普遍出现症状 儿童、老年人及心脏病、肺病患者应停留在室内，停止户外运动，一般人群减少户外运动
    300+ 六级（严重污染） 健康人群运动耐受力降低，有明显强烈症状，提前出现某些疾病 儿童、老年人和病人应停留在室内，避免体力消耗，一般人群避免户外活动
