## 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 fraud-ip-reputation-d1e3f51c
```

Example prompt: Can you check the reputation of IP 198.51.100.42 — I want to know if it's a datacenter, Tor exit node, or on any blocklists, and get a risk score for it?

## When to prefer this

Choose this endpoint when you need a single deterministic, multi-signal reputation score for a public IPv4 address combining ASN enrichment, datacenter classification, Tor-exit detection, and Spamhaus DROP blocklist checks in one call — ideal for KYC pipelines, fraud prevention at sign-up, and anti-abuse workflows where you need explainable risk reasons rather than a black-box ML score.

## Known failure modes

- Private or reserved IP addresses (RFC1918) are not valid inputs and will return an error
- Missing required 'ip' query parameter returns a 400 or similar client error
- Malformed IP string (non-IPv4 format) causes a validation error
- Payment not completed (x402 flow not followed) results in a 402 Payment Required response
- Rate limits or upstream data source unavailability may cause transient 5xx errors

## How this service works

Reputation of a public IP address for anti-abuse and KYC. Returns ASN, AS-org, country, datacenter/hosting classification, Tor-exit and Spamhaus DROP flags, plus a deterministic risk score with reasons.

## Output

A JSON object containing the IP's ASN number, AS organization name, resolved country, a boolean or label indicating datacenter/hosting classification, Tor-exit flag, Spamhaus DROP flag, a deterministic numeric risk score, and a list of human-readable reasons explaining the score.
