When using GoProxy’s rotating proxies, you can specify the IP’s country, region, or city.

curl -U "customer-<username>-country-<country_code>:<password>" -x "proxy.goproxy.com:30000" "https://target.domain"
The country_code is the two-character ISO 3166-1 country code. You can use the Endpoint Generator on the Dashboard to automatically generate the code.
