CashoutGuard vs proxycheck.io
Going beyond IP checks on rewards and GPT sites
proxycheck.io is cheap, simple and a favourite of GPT scripts for blocking VPNs and proxies. It checks IP addresses, and it does that job well.
The short version
proxycheck.io tells you whether an IP is a proxy or VPN. CashoutGuard adds the device, the linked accounts and the cashout, which is where residential proxies stop working.

What proxycheck.io does well
- Very low prices and a free tier of 1,000 queries per day.
- A simple API that many GPT scripts already support.
- Good at catching VPN, proxy and hosting IP addresses.
What rewards sites still need on top
- It checks IP addresses only: no device, no account linking and no payout address checks.
- Residential proxies look like home connections, so IP-only checks miss them.
- Prices went up on October 1, 2026: the cheapest paid plan is now $4.99/month.
- It does not model offers, postbacks or cashouts, and there is no review queue.
Pick proxycheck.io if
- Your budget is close to zero and you only need to block obvious VPN and datacenter IPs at signup.
- You have few users and review every cashout by hand anyway.
Pick CashoutGuard if
- Farmers get past your VPN check with residential proxies or real phones.
- You see many accounts paying out to the same wallet or PayPal.
- You want one decision per cashout instead of stitching IP checks into your own rules.
Why rewards sites switch
Catches what IP lists miss
When the IP looks clean, a shared device, payout address or impossible offer speed still links the accounts.
VPN detection is still included
Tor, VPN and datacenter IPs, timezone mismatch and WebRTC leaks are part of every score.
Still free for small sites
The free plan covers 1,000 monthly active users with every signal, so trying it costs nothing.
