# AgentRXI IP & ASN Lookup (RDAP)

> AgentRXI IP & ASN Lookup (RDAP) is a paid API for AI agents from agentrxi.com, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-15).

Looks up IP address or ASN metadata from internet registries (RDAP), returning network name/range, owning organization, country, origin ASN, abuse contact, registration dates, and reverse DNS.

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 agentrxi-ip-asn-lookup-rdap-80555d30
```

Example prompt: Who owns the IP address 8.8.8.8? I want to know the organization, country, network range, and abuse contact email from the internet registries.

## When to prefer this

Use this endpoint when you need authoritative internet registry (RDAP) data for an IP address or ASN — including ownership, network range, country, and abuse contact — rather than GeoIP databases which focus on geolocation accuracy. Prefer this for cybersecurity, abuse reporting, network research, or compliance use cases where registry-sourced data is required.

## Known failure modes

- Invalid or malformed IP/ASN input returns an error
- Private or reserved IP ranges (e.g. 192.168.x.x, 10.x.x.x) may return no or limited RDAP data
- Some ASNs or IP blocks may have incomplete registry data
- RDAP registry may be temporarily unavailable, causing timeout or 5xx errors
- Both ip= and asn= omitted returns a parameter error

## How this service works

IP address and ASN lookup from the internet registries (RDAP): network name and range, owning organization, country, origin ASN, abuse contact email, registration dates and reverse DNS. Pass ip= (IPv4/IPv6) or asn=.

## Output

Returns structured RDAP data including network name, IP range/CIDR block, owning organization, country code, origin ASN, abuse contact email address, registration and last-updated dates, and reverse DNS hostname for the queried IP or ASN.
