## 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 api-strale-io-93056f85
```

Example prompt: Can you check whether the IP address 104.28.42.1 is suspicious — is it a VPN, proxy, Tor exit node, or datacenter IP, and what's the overall fraud risk score?

## When to prefer this

Use this endpoint when you need to assess the fraud or abuse risk of a specific IP address during user signup, login, or transaction flows — especially when you need to detect anonymization techniques like VPNs, proxies, or Tor. Prefer this over generic geolocation APIs when the primary goal is fraud risk rather than location.

## Known failure modes

- Invalid or malformed IP address returns a validation error
- IPv6 addresses may not be fully supported by all detection databases
- Private or reserved IP ranges may return incomplete results
- Network timeout or service unavailability returns a 5xx error
- Missing required 'ip' query parameter returns a 400 error

## How this service works

Assess fraud risk for an IP address. Detects VPNs, proxies, Tor exit nodes, hosting/datacenter IPs. Returns risk score and risk factors.

## Output

Returns a numerical fraud risk score and a set of risk factors indicating whether the IP is associated with a VPN, proxy, Tor exit node, or hosting/datacenter infrastructure.
