## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability compliapi-vpn-detection-283b4bbd
```

Example prompt: Before I process this transaction from IP 203.0.113.7, can you check if that IP is using a VPN or proxy?

## When to prefer this

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.

## Known failure modes

- 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

## 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}.
