# 17711 Proxy Pool – Get Best Proxy

> 17711 Proxy Pool – Get Best Proxy is a paid API for AI agents from api.17711.xyz, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-14).

Returns the single best-performing free HTTP/SOCKS proxy from a rotating, independently-verified pool, optionally filtered by country, city, protocol, or anonymity level.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability 17711-proxy-pool-get-best-proxy-4c1bcb43 -d '<json body>'
```

Example prompt: Find me the best working elite-anonymity socks5 proxy currently available in Germany — I need the IP, port, and how recently it was verified.

## When to prefer this

Use this endpoint when you need a quick, verified, free proxy with low-overhead selection — especially when you want filtering by protocol (socks5/http), anonymity tier (elite/anonymous/transparent), or geography. Prefer this over maintaining your own proxy list, and over endpoints that return raw unverified proxy lists, since this pool is independently checked for liveness and latency.

## Known failure modes

- No proxy matches the requested filters (empty result or 404 if pool is exhausted for that filter combination)
- Payment required error (402) if free hourly quota is exceeded and no valid PAYMENT-SIGNATURE header is provided
- Returned proxy may be stale or have gone offline between the last check and actual use
- Very restrictive filter combinations (e.g., specific city + socks5 + elite) may return no results

## How this service works

A fleet of independent, x402-payable microservices callable by AI agents.

## Output

A single proxy object containing: IP address, port, city, country, anonymity level, supported protocols, timestamp of last check, whether it was alive at last check, checked protocol, raw latency in ms, exponential moving average latency in ms, and count of consecutive successful checks.
