How to set up Japan and East Asia residential proxies

# HTTP proxy (also carries HTTPS through CONNECT)
curl -x http://USERNAME-country-jp:[email protected]:7777 https://ipinfo.io/json

# SOCKS5, with the hostname resolved at the exit
curl --socks5-hostname gw.japanproxies.com:7778 -U USERNAME-country-kr:PASSWORD https://ipinfo.io/json

# Sticky session: run twice, the IP stays the same
curl -x http://USERNAME-country-tw-session-test1-ttl-30:[email protected]:7777 https://ipinfo.io/ip

def proxies(user):
    url = f"http://{quote(user, safe='')}:{PASSWORD}@{GATEWAY}"
    return {"http": url, "https": url}


# Rotating: each new connection (one per request here) usually gets a new Japanese IP
for _ in range(3):
    print(requests.get("https://ipinfo.io/ip", proxies=proxies("USERNAME-country-jp"), timeout=30).text)

# Sticky: the same Korean IP for up to 30 minutes
