How this service works
Easy OFAC sanction list lookups, geo-fencing checks and VPN detection, streamlining compliance obligations around the world.
Output
Returns a JSON object with the queried IP address and a boolean 'vpn' field indicating whether the IP is associated with a VPN, proxy, or other anonymization service. Example: {"ip": "203.0.113.7", "vpn": false}.
Example use cases
Block VPN users from regulated service
“A user just tried to sign up from IP 198.51.100.42 — can you check if they're using a VPN or proxy before I let them through? We can't allow anonymized connections under our compliance policy.”
Fraud detection before payment processing
“We're about to process a payment from IP 192.0.2.15 — run a VPN check on it first so we can flag it if the user is hiding their real location.”
Geo-restriction enforcement check
“Someone from IP 203.0.113.99 is trying to access our geo-restricted content — check whether they're using a VPN to bypass the restriction.”
Technical details
Endpoint
GEThttps://api.compliapi.com/api/v1/vpnWhen to prefer
Choose this endpoint when you need a lightweight, real-time check on whether an IP address is using a VPN or proxy — particularly in compliance, fraud prevention, or geo-restriction enforcement workflows. It is ideal for pre-transaction screening, onboarding gating, or regulatory access control where anonymization detection is required. Prefer this over full KYC services when the only question is network-layer anonymization rather than identity verification.
Side effects
- Invalid or malformed IP address returns an error response
- Private/reserved IP ranges may return unexpected results
- VPN services using residential IPs may evade detection
- Rate limiting or payment failure returns 402 or 429 status
- Newly provisioned VPN exit nodes may not yet be in the database
