## 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 polyform-ip-rdap-lookup-5eb51cd5
```

Example prompt: Who operates the IP address 8.8.8.8 — what organization owns it, which country is it in, and what network range does it belong to?

## When to prefer this

Use this endpoint when you need structured, authoritative IP ownership data (organization, network range, registry, country) sourced directly from RIR RDAP — preferred over informal WHOIS text parsing when you need clean JSON output and don't need geolocation coordinates or abuse contact details.

## Known failure modes

- Invalid or malformed IP address returns an error
- Private/reserved IP ranges may not have RDAP records
- Some RIRs may be temporarily unavailable causing lookup failures
- Very new IP allocations may not yet appear in RDAP
- IPv6 addresses may have varying levels of RDAP detail

## How this service works

Who operates an IP: registry, network range, organization, country. Source: RIR RDAP. JSON.

## Output

A JSON object containing the RIR RDAP record for the IP, including the managing registry, allocated network range (CIDR), the registered organization name, and the country of registration.
