How this service works
Detect whether an IP address is using a VPN, proxy or other anonymization service. Call before trusting an IP's geolocation for compliance rules, fraud checks or access gating. Returns vpn true/false, or "unknown" when no privacy data exists for the IP.
Output
Returns a JSON object indicating whether the IP address is using a VPN, proxy, or other anonymization service. The `vpn` field is `true` if anonymization is detected, `false` if it is not, or `"unknown"` if no privacy data exists for that IP.
Example use cases
Fraud check during checkout
“The order just came in from IP 185.220.101.45 — can you check if that IP is running through a VPN or proxy before I approve the payment?”
Geolocation trust before access gating
“We block users from certain countries due to licensing restrictions — can you check if 198.54.117.200 is using a VPN so I know whether to trust its reported location?”
Onboarding compliance verification
“A new user just signed up and their IP is 91.108.4.1 — can you tell me if that IP is anonymized or behind a proxy before I run the rest of the compliance checks?”
Technical details
Endpoint
GEThttps://api.compliapi.com/api/v1/vpn/:ip_address?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, per-IP check on whether a connecting client is hiding their real location behind a VPN, proxy, or anonymization service — particularly before applying geolocation-dependent compliance rules, fraud scoring, or access gating. It is purpose-built for compliance workflows alongside sibling endpoints for sanctions screening, geolocation, and wallet screening on the same platform.
Side effects
- IP address not found or no privacy data available — returns unknown rather than true/false
- Invalid IP address format — likely returns an error or bad-request response
- Rate limiting or quota exhaustion — HTTP 429 or payment required
- Newly allocated or private IP ranges may consistently return unknown
