# IP Reputation & Risk Scoring

> IP Reputation & Risk Scoring is a paid API for AI agents from api.agentstools.dev, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-14).

Returns ASN, AS organization, country, datacenter/hosting classification, Tor-exit and Spamhaus DROP flags, and a deterministic risk score with reasons for a given public IPv4 address.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 ip-reputation-risk-scoring-9937625b
```

Example prompt: Before I onboard this user, can you check whether IP address 203.0.113.47 is high-risk — I want to know if it's a datacenter, Tor exit node, or on any abuse blocklist, and what risk score it gets?

## When to prefer this

Use this endpoint when you need a quick, structured reputation verdict on a public IPv4 address for fraud prevention, KYC workflows, or anti-abuse gating. It is preferable over general IP geolocation APIs when you specifically need abuse signals like Tor-exit status, Spamhaus DROP membership, hosting/datacenter classification, and a combined risk score with reasons in a single call.

## Known failure modes

- Private or reserved IP address provided — endpoint expects a public IPv4
- Invalid IP format (e.g. IPv6 or malformed string) — likely returns 400 bad request
- IP not found in ASN databases — may return partial data or unknown fields
- Network timeout or upstream lookup failure — may return 5xx error
- Missing required 'ip' query parameter — returns 400 or validation error

## 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 structured object containing the IP's ASN number, AS organization name, resolved country, whether it's classified as a datacenter or hosting IP, boolean flags for Tor exit node status and Spamhaus DROP list membership, a deterministic numeric risk score, and a list of human-readable reasons driving that score. Optionally includes a geo-mismatch flag if a claimed country was provided.
