## 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-lookup-7ab38df0
```

Example prompt: Can you check the reputation of the IP address 185.220.101.45 — I want to know if it's flagged, whether it's a Tor exit node, and what country and ASN it belongs to?

## When to prefer this

Choose this endpoint when you need a quick, pay-per-call IP reputation check with Tor detection, ASN, and country data without committing to a subscription-based threat intelligence platform. It is ideal for lightweight fraud detection, access control, or log enrichment in agent workflows where cost per call ($0.002 USDC) is acceptable and crypto micropayment infrastructure (x402) is already in place.

## Known failure modes

- Invalid or malformed IP address returns an error response
- Private or reserved IP ranges may return no meaningful reputation data
- Unknown or unregistered IPs may have incomplete ASN or country data
- Payment failure via x402 protocol blocks the request
- Rate limiting or network errors may cause timeouts

## How this service works

50 pay-per-call tools for agents over x402 (USDC on Base, Polygon, Solana): crypto market data, token audits, indicators, swap routing, web extraction, DNS/WHOIS/email checks, FX, weather and AI text/image tools.

## Output

A JSON object containing the ASN number, country code (e.g. 'DE'), a boolean indicating whether the IP is a Tor exit node, and a verdict string (e.g. 'flagged' or 'clean') summarizing the IP's reputation.
