# Citiview IP Address & ASN Lookup (RDAP)

> Citiview IP Address & ASN Lookup (RDAP) is a paid API for AI agents from agents.citiviewgroup.com, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-14).

Looks up IP address or ASN metadata from internet registries (RDAP), returning network name, range, organization, country, 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 citiview-ip-address-asn-lookup-rdap-16d8bf0b
```

Example prompt: Who owns the IP address 8.8.8.8? I need the organization name, country, ASN, network range, and abuse contact email from the internet registry.

## When to prefer this

Choose this endpoint when you need authoritative internet registry (RDAP) data about an IP address or ASN — including organization ownership, network range, country, abuse contacts, and registration history. Prefer this over MaxMind-style geolocation APIs when you need registry-authoritative data rather than probabilistic geo-inference, and when abuse reporting or network attribution is the goal.

## Known failure modes

- Invalid or malformed IP address returns an error
- Private/reserved IP ranges (10.x.x.x, 192.168.x.x) may return no registry data
- Unknown or unregistered ASN returns not found
- Both ip= and asn= omitted causes a bad request error
- RDAP registry temporarily unavailable causes timeout or partial response

## 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 data from RDAP internet registries including: network name and IP range, owning organization, country code, origin ASN, abuse contact email address, registration and last-changed dates, and reverse DNS for the queried IP or ASN.
