Use these copy-paste examples to send your first authenticated request through Roundproxies. Replace USERNAME, PASSWORD, and the gateway host with the values from your dashboard.
Credentials are tied to your account. Grab them from the dashboard before running any of the snippets below.

​
Proxy Endpoint

All examples on this page point at the same gateway. Adjust the host and port to match the network you’re using (residential, datacenter, or ISP). 
http://USERNAME:PASSWORD@gate.roundproxies.com:8000

​
Python

The requests library is the most popular choice for synchronous scraping in Python. 
import requests

proxies = {
    "http":  "http://USERNAME:PASSWORD@gate.roundproxies.com:8000",
    "https": "http://USERNAME:PASSWORD@gate.roundproxies.com:8000",
}

r = requests.get("https://httpbin.org/ip", proxies=proxies, timeout=30)
print(r.json())

​
Node.js

Use axios together with https-proxy-agent to route both HTTP and HTTPS traffic through the gateway. 
import axios from "axios";
import { HttpsProxyAgent } from "https-proxy-agent";

const agent = new HttpsProxyAgent(
  "http://USERNAME:PASSWORD@gate.roundproxies.com:8000"
);

const { data } = await axios.get("https://httpbin.org/ip", {
  httpAgent: agent,
  httpsAgent: agent,
});

console.log(data);

​
Go

The standard net/http package supports proxies out of the box via http.ProxyURL. 
package main

import (
	"fmt"
	"io"
	"net/http"
	"net/url"
)

func main() {
	proxyURL, _ := url.Parse("http://USERNAME:PASSWORD@gate.roundproxies.com:8000")
	client := &http.Client{
		Transport: &http.Transport{Proxy: http.ProxyURL(proxyURL)},
	}

	resp, _ := client.Get("https://httpbin.org/ip")
	defer resp.Body.Close()
	body, _ := io.ReadAll(resp.Body)
	fmt.Println(string(body))
}

​
PHP

PHP’s bundled cURL bindings make routing requests through Roundproxies a one-liner. 
<?php
$ch = curl_init("https://httpbin.org/ip");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_PROXY, "gate.roundproxies.com:8000");
curl_setopt($ch, CURLOPT_PROXYUSERPWD, "USERNAME:PASSWORD");

echo curl_exec($ch);
curl_close($ch);

​
Ruby

The standard library’s Net::HTTP::Proxy factory wraps Net::HTTP with proxy auth. 
require "net/http"
require "uri"

uri   = URI("https://httpbin.org/ip")
proxy = Net::HTTP::Proxy(
  "gate.roundproxies.com", 8000, "USERNAME", "PASSWORD"
)

puts proxy.get_response(uri).body

cURL

The fastest way to verify your credentials from a shell. 
curl -x "http://USERNAME:PASSWORD@gate.roundproxies.com:8000" \
     https://httpbin.org/ip
