VPNAPI.io review
A hosted IP lookup API for location, network details, and anonymization signals.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
VPNAPI.io is a hosted IP-intelligence API for developers building applications that classify visitor locations or flag potentially anonymized IP addresses. A lookup by IP returns geolocation, network and autonomous-system information, along with indicators for VPN, proxy, Tor, and relay usage. It is suited to teams that need these signals through a straightforward API rather than a broader IP research workflow.
Its scope is centered on a single lookup: IP address in, structured location and network intelligence out. Geolocation includes city, country, and coordinates; network classification covers hosting, while ASN and organization information add context about the address. REST access makes it usable from applications that can send HTTP requests with an API key. The service is cloud hosted, with web and API listed as platforms, and documentation and email as support channels. This narrow API-first shape is a fit when an application needs to check addresses as part of its own flow, but less suitable for buyers seeking a wider integrated investigation environment.
The published Free plan includes IP geolocation and security API access, with a 1,000-lookup allowance. That gives small projects a way to evaluate or support limited-volume use, but the allowance may constrain services checking many visitor addresses. Pricing is freemium, and plan details beyond Free should be compared directly before budgeting. Choose VPNAPI.io when location, VPN/proxy/Tor/relay detection, and network classification are the required outputs; look elsewhere if higher-volume capacity or broader workflow and integration coverage is central to the decision.
