cURL and Proxy Testing
cURL is the universal command-line HTTP client — pre-installed on macOS, Linux, and Windows 10+. It is the fastest way to test proxy connectivity, verify your IP rotation, debug API requests, and validate proxy credentials without writing any code.
cURL supports HTTP, HTTPS, SOCKS4, and SOCKS5 proxies natively with full authentication support via simple command-line flags.
Prerequisites
- cURL: version 7.21.7 or later (for SOCKS5 support)
- Proxy Gateway:
gate.turboproxy.online - Port: e.g.,
7000 - Username / Password: From your Turbo Proxy dashboard
Check your cURL version: curl --version
Command Examples
Basic HTTP Proxy
curl -x http://gate.turboproxy.online:7000 \
-U your_username:your_password \
https://api.ipify.org?format=jsonSOCKS5 Proxy (Recommended)
curl --socks5 gate.turboproxy.online:7000 \
-U your_username:your_password \
https://api.ipify.org?format=jsonSOCKS5 with Remote DNS (Avoid DNS Leaks)
curl --socks5-hostname gate.turboproxy.online:7000 \
-U your_username:your_password \
https://api.ipify.org?format=jsonProxy in URL Format (Inline Credentials)
curl -x "http://your_username:[email protected]:7000" \ https://api.ipify.org?format=json
Test with Custom Headers (Mimic Browser)
curl --socks5-hostname gate.turboproxy.online:7000 \
-U your_username:your_password \
-H "User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36" \
-H "Accept-Language: en-US,en;q=0.9" \

for i in {1..5}; do
echo -n "Request $i: "
curl -s --socks5-hostname gate.turboproxy.online:7000 \

export http_proxy="http://your_username:[email protected]:7000" export https_proxy="http://your_username:[email protected]:7000" # Now all curl commands use the proxy automatically curl https://api.ipify.org?format=json
Troubleshooting
1. "Could not resolve proxy" error
Make sure your DNS can resolve gate.turboproxy.online. Try nslookup gate.turboproxy.online to verify. If using SOCKS5, use --socks5-hostname to let the proxy handle DNS.
2. SSL certificate verify failed
Only for testing: add -k flag to skip SSL verification. Do not use in production. This is usually caused by an outdated CA bundle — update with brew upgrade curl (macOS) or your package manager.
