Authentication
After signing up at the dahsboard, you will get your access token. In below sections, we will use a temporary token for demo purpose: S45Fnpxcwyq0QT4b. In production or development, you should use your own.
API request
We support json and jsonp
-

https://api.caiyunapp.com/v2.5/S45Fnpxcwyq0QT4b/-157.8583,21.3069/weather.jsonp&callback=CALLBACK
Parameters
- lang: optional, the language, default value is
zh_CN, you can set any one ofzh_CN,zh_TW,en_US,en_GB,ja - unit: optional, the unit system, default value is
metric, you can set any one ofmetric,imperial,SI - granu: optional, the temporal granularity, default value is
realtime,minutely,hourly,daily, you can set any one or combinations ofrealtime,minutely,hourly,daily - hourlysteps: optional, how many hours will be present in hourly forecast, default value is
48hours and maximal value is360hours

API response
To understand the API response better, you should know all the variables and the control parameter granu.
The supported variables
All the supported variables are physical variables on or near earth's surface
- temperature
- precipitation: a group of variables
- wind: speed and direction
- humidity: relative humidity
- pressure
- visibility: horizontal visibility on earth's surface
- dswrf: downward shortwave radiation flux
- air quality group: including aqi, pm25 and others
- life index group: indicators for comfort or not, or status of ultraviolet radiation
and also skycon
- skycon: it is a collection of short descriptive code of weather phenomenon on earth surface introduce by DarkSky and was released into public domain.
The heading part
The heading part gives you basic settings of the API response, it is the start point of any weather calculation.

lang: en_US # The i18n language parameter in response, supported languages are include en_US, en_GB, zh_CN, zh_TW, ja
unit: imperial # The i18n unit parameter in response, supported unit system are include metric, imperial and SI
tzshift: -14400 # Timezone shift measured in seconds
timezone: America/New_York # Timezone
server_time: 1585894300 # Server time measured in unix timestamp or total seconds from 1970-01-01 00:00:00

- -74.006 # The requested longitude
You should notice that this API are latitude-longitude based, we do not support city-based queries.
