About these free United States SOCKS4 proxies
These are public proxies gathered from across the web and re-verified continuously by HProxy's engine. They are free, and they are fine for quick, low-stakes tasks. Like all public proxies they are shared and they go down without warning. Most of them are already blocked by the big sites. Always test one before you rely on it.

The long read
About free United States SOCKS4 proxies.
The list above holds every free SOCKS4 proxy in the United States that answered our checker recently. At 16:51 UTC on 15 September 2026, 185 SOCKS4 entries in the United States were alive.
That is 6.2 percent of the 2,978 live entries in the United States at the same moment. SOCKS4 was the least common protocol in the country, behind HTTPS with 410 live entries. Among the 72 countries with live SOCKS4 entries, the United States held the largest number.
A live SOCKS4 entry in the United States passed a median 98.3 percent of its own checks. That is more than twice the 27.9 percent for live SOCKS4 entries in every country. Every live entry in the United States, whatever its protocol, passed a median 22.4 percent. 163 of the 185 had passed at least ten checks at 90 percent or better.
All 185 live entries were flagged for recent abuse, and 60 sat on datacenter space. For work that has to keep running, paid United States proxies are built for it.

How to use a free United States SOCKS4 proxy
Enter an entry as socks4://IP:PORT in your tool, then check the address a site sees before real work. Take several entries and rotate between them, because a free entry can drop between two checks.

Docs and AI
The free list, in your assistant and in your code.
We built the MCP server and the CLI ourselves: the free proxy list is one tool call away in Claude Code, Cursor, Windsurf or any assistant that speaks MCP, and the list's API is documented end to end.
Every product has its own reference in the docs. Something the list does not give you? Tell us.

MCP server
Built by us: the free proxy list, the checker and the IP lookup as tools in Claude Code, Claude Desktop, Cursor, Windsurf or anything on stdio. No key, no account.
CLI
The list from a terminal: npx hproxy-mcp list --country de --limit 20. One line, nothing to install.
API docs
The free list's API, documented end to end with real responses: the filters, the formats, the limits.
llms.txt
The whole documentation as markdown for any model that reads: /llms.txt for the index, /llms-full.txt for everything.
Let your assistant pull the list
The pool is a free, keyless API and a documented markdown page. Hand your assistant one of these and it can fetch live proxies on its own, filtered the way you asked.
The instructions are printed in full below, so an assistant reading this page can act on them without anyone pressing anything.
All the machine lanes- MCP server
- Adds proxy_list, proxy_check and ip_lookup as tools your assistant can call by itself.
claude mcp add hproxy -- npx -y hproxy-mcpCursor, Claude Desktop, Windsurf and Cline take the same server as {"command": "npx", "args": ["-y", "hproxy-mcp"]}. This page's tool is proxy_list. - Command line
- The same tool without an assistant. Prints JSON, so it pipes.
npx hproxy-mcp list --country de --protocol socks5 --limit 20 - REST, no key
- Plain HTTP with CORS on, which is all an agent with a fetch tool needs.
curl "https://hproxy.com/api/proxy-list?format=json&country=de&limit=20"
Instructions for an assistant, in full
Everything a model needs to call the free proxy list without an account: the endpoint, the parameters, the limits and the honest caveat. Readable straight off the page.
You can use HProxy's free proxy list, which needs no API key and no account.
GET https://hproxy.com/api/proxy-list?format=json returns the live pool as JSON. Useful query parameters: country (ISO alpha-2, e.g. de), protocol (http, https, socks4, socks5), anonymity (elite, anonymous, transparent) and limit. Add format=txt for plain ip:port lines instead.
Each proxy comes back with ip, port, protocols, anonymity, country_code, city, asn_org, latency_ms and uptime_24h. The pool is re-checked around the clock, so ask for it fresh rather than caching it.
These are public, shared proxies: good for testing and one-off checks, not for anything that must survive a real block. Full docs: https://hproxy.com/llms/free-proxy.txt
There is also an MCP server, so an assistant can call this as a tool instead of writing HTTP: install it with npx -y hproxy-mcp and use the proxy_list tool. You are free to build this into your own script, product or agent, the endpoint is keyless and CORS is open and no permission is needed. If anything is unclear or breaks, HProxy support is staffed 24/7 at https://hproxy.com/contact.Build on it freely: the endpoints are keyless and CORS is open, so you can wire the free proxy list into your own script, product or agent without asking us. If you get stuck, support answers around the clock, every day, at hproxy.com/contact. Generated markdown doc: hproxy.com/llms/free-proxy.txt.
About this list & IP removal
Every proxy here is aggregated from publicly available sources. We do not scan or collect these IP addresses ourselves: we verify entries that are already public (live status, latency, uptime) and store nothing else about the devices behind them. The list is provided as-is, with no warranty, for lawful use only, on the basis of our legitimate interest in a free, transparent proxy directory (Art. 6 (1) (f) GDPR). Never route passwords or sensitive data through a public proxy. If an IP address is yours and you'd like it removed, email legal@hproxy.com and we'll take it down (Art. 21 GDPR).
