Proxy / VPN Detection API
Detect VPNs, proxies, datacenters, and Tor exit nodes with real-time risk scoring.
Analyze any IP address to identify known VPNs, proxies, datacenters, or Tor exit nodes. This API provides a risk score and identifies providers like AWS, Google Cloud, or NordVPN to prevent fraud and bot abuse. No external API calls — 100% server-side.
How it works
Three steps. No complex setup.
Validación de IP
Se verifica que la IP tenga formato válido (IPv4 o IPv6) y se detectan automáticamente IPs privadas y de loopback.
Comprobación de nodos Tor
Se verifica contra una lista de nodos de salida de Tor conocidos. Los nodos Tor reciben el risk_score más alto (95).
Detección de rangos VPN
Se comprueba contra rangos de IP conocidos de los principales proveedores de VPN comerciales (NordVPN, ExpressVPN, Mullvad, ProtonVPN, Surfshark).
Identificación de datacenters
Se detectan rangos de los principales proveedores cloud (AWS, Google Cloud, Azure, DigitalOcean, Hetzner, OVH, Vultr, Linode) y se asigna un risk_score moderado.
