## 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-address-lookup-bab39af8
```

Example prompt: Can you look up who owns the IP address 104.21.45.22 — I need the ASN, network holder, country, city, and reverse DNS?

## When to prefer this

Choose this endpoint when you need a quick, pay-per-call IP enrichment with comprehensive network metadata (ASN, prefix, RIR, geo, rDNS) in a single call, without committing to a subscription. Ideal for fraud checks, log enrichment pipelines, or one-off host identification tasks where you need more than just geolocation — especially when ASN and network ownership data are required.

## Known failure modes

- Invalid or malformed IP address returns an error
- Private/reserved IP ranges (e.g. 192.168.x.x) may return no geolocation data
- Hostname that cannot be resolved returns DNS failure
- Payment failure or insufficient USDC balance blocks the request
- Rate limiting may occur under high request volume

## How this service works

Who owns an IP address (or a hostname's IP): ASN, network holder, announced prefix, regional registry, country, approximate city and coordinates, reverse DNS. Use for fraud checks, log analysis or finding a site's host.

## Output

Returns structured data including: ASN number and name, network holder/organization, announced IP prefix, regional internet registry (RIR), country, approximate city and lat/lon coordinates, and reverse DNS (PTR record) for the queried IP or the resolved IP of a hostname.
