Ipxapi Blog: #1 Accurate IP Address Lookup and Geolocation API

A VPN detection API is a REST endpoint that returns boolean security flags for an IPv4/IPv6 address. On ipXapi those flags live on GET /api/ip?ip= inside the security object: is_vpn, is_proxy, is_tor, plus cloud, bogon, and threat bits. Auth is Authorization: Bearer YOUR_KEY. The official response example on the test-drive docs uses 148.105.12.120 (MailChimp / AS14782, Mountain View, CA). In that fixture is_vpn is false and is_cloud_provider is true — do not treat cloud as VPN. Basic is $29.99/mo. Trial is 7 days or 50 requests, whichever comes first. Playground: ipxapi.com.
