## 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 payperscreen-ip-risk-check-37cfa612
```

Example prompt: Can you run a risk check on the IP address 203.0.113.42 to see if it looks suspicious or is associated with fraud?

## When to prefer this

Choose this endpoint when you need a quick, pay-per-call IP reputation check without a subscription, especially in fraud prevention, user onboarding, or transaction monitoring flows where you only need to screen occasional or high-value IPs. It complements PayPerScreen's other screening tools (email trust, sanctions, crypto address) for a multi-signal risk picture.

## Known failure modes

- Invalid or private IP address provided — endpoint expects a public IPv4 address
- Missing required 'ip' query parameter returns an error
- IPv6 addresses may not be supported (IPv4 only per schema)
- Unknown or unresolvable IP may return low-confidence results
- Beta status means output schema and reliability may change without notice
- Rate limits or payment failures may cause 402/429 errors

## How this service works

Check names, crypto wallets, emails and IP addresses against official sanctions lists and risk signals. 2 cents a check, no contract, no account. Built so your software, or your AI agent, can run it on every customer and every payment.

## Output

Returns a risk assessment for the given IPv4 address, likely including risk score, flags for VPN/proxy/Tor usage, abuse history, geolocation signals, and an overall risk verdict indicating whether the IP is safe or suspicious.
