Introducing VPN & Proxy Detection API: Classify IP Addresses as VPN, proxy, residential proxy, or something else

TL;DR

  • WhoisXML API’s VPN & Proxy Detection API is a new real-time API with daily bulk data files that classifies IPv4 addresses as VPN, proxy, residential proxy, Tor, relay, hosting, or CDN traffic. 
  • One of the things that sets the API apart is residential-proxy detection that mainstream IP-intelligence databases miss; about 88% of those detections are independently confirmed by a third-party source.
  • The API is live now, with pricing starting as low as $1/month. Sign up to get an API key within minutes.

Disposable Email Domains Database: Improved Detection with 99% Precision

TL;DR

  • The Disposable Email Domains Database has been upgraded with a more precise machine learning detection model that reaches 99% tested detection precision.
  • It adds scoring for every domain on a scale from 0 to 100, allowing you to set your own block, verify, and allow thresholds based on the score.
  • It tracks 162,000+ disposable domains and is refreshed daily in CSV and JSON.

New Account Controls: IP Allowlist and Per-Member Usage Monitoring

TL;DR

  • You can now restrict API requests and database or data feed downloads to a list of trusted IP addresses, so a leaked or shared key alone is no longer enough for unauthorized users to use your API key.
  • Enterprise account administrators using Parent-Child API keys can see API usage broken down by individual team member or combined for the whole account.
  • Both are available now in your account settings. The IP allowlist is off by default, and your account setup stays the same.
