well there is echo module for nginx which definitely help you with more complex json. If all you want is IP in json format you could try something like this with pure nginx(untested)

location /json {
  default_type application/json;
  return 200 '{"ipaddress":"'$remote_addr'"}';
}

It's also possible via DNS:

For IPv4:

dig -4 +short -t a myip.opendns.com @resolver1.opendns.com

And for IPv6:

dig -6 +short -t aaaa myip.opendns.com @resolver1.opendns.com

host -4 myip.opendns.com resolver1.opendns.com
host -6 myip.opendns.com resolver1.opendns.com

curl ip.sb

curl ipinfo.io is the most useful

You can also avoid all the HTTP 'overhead' by using a simple DNS query to achieve the same:

alias myip4="dig @208.67.220.220  @208.67.222.222  myip.opendns.com A    +short"
alias myip6="dig @2620:119:35::35 @2620:119:53::53 myip.opendns.com AAAA +short"
