Would you be interested in adding ISO_3166-1 alpha-2 or alpha-3 country codes? E.g. extending:

"coordinates" : "{...}"
"country"  "Mainland China"
"history" : "{...}"
"latest" : 990
"province" : "Anhui"

by

"alpha-2 code" : "CN" 
"alpha-3 code" : "CHN" 

My telegram bot https://t.me/corona_cases_bot needs it, and I consider what is better - implemented in mine or your project?
