Detect VPN, Proxy & Tor in Rust

No dedicated call needed — the fields ride along with a normal lookup_ip.

let client = Client::new(std::env::var("IP_API_IO_KEY")?);

let info = client.lookup_ip("185.220.101.1").await?;
let f = &info.suspicious_factors;

println!("{}", f.is_vpn);        // VPN service
println!("{}", f.is_proxy);      // open / anonymizing proxy
println!("{}", f.is_tor_node);   // Tor node
println!("{}", f.is_datacenter); // hosting / datacenter IP (often a bot)
println!("{}", f.is_spam);       // known spam source
println!("{}", f.is_crawler);    // known crawler / bot
println!("{}", f.is_threat);     // listed on a threat feed

if f.is_vpn || f.is_proxy || f.is_tor_node {
    // require step-up verification (CAPTCHA, 2FA)
}

A dedicated check against the live Tor node list, with a count of matching nodes.

let tor = client.tor_check("185.220.101.1").await?;

println!("{}", tor.is_tor);         // true
println!("{}", tor.tor_node_count); // number of matching Tor nodes
