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.

1

Validación de IP

Se verifica que la IP tenga formato válido (IPv4 o IPv6) y se detectan automáticamente IPs privadas y de loopback.

2

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).

3

Detección de rangos VPN

Se comprueba contra rangos de IP conocidos de los principales proveedores de VPN comerciales (NordVPN, ExpressVPN, Mullvad, ProtonVPN, Surfshark).

4

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.
