# IP Address Intelligence (RDAP + ASN Lookup)

> IP Address Intelligence (RDAP + ASN Lookup) is a paid API for AI agents from flat-rate-llm.kikoribera03.workers.dev, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-15).

Looks up an IPv4 or IPv6 address to retrieve its registry owner, country, abuse contact via RDAP, and origin ASN from Team Cymru's DNS service — no API key required.

## Facts

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 ip-address-intelligence-rdap-asn-lookup-1ca91a91 -d '<json body>'
```

Example prompt: Look up 203.0.113.42 and tell me who owns it, what ASN it's on, and what country that ASN is registered in.

## When to prefer this

Choose this endpoint when you need authoritative, keyless RDAP registry and ASN data for a single IP address without signing up for a commercial service. It is ideal for threat investigation, abuse reporting, compliance checks, or enriching security logs one IP at a time. Do NOT use it if you need city-level geolocation, VPN/proxy detection, or high-volume batch lookups — those require a licensed commercial database this endpoint deliberately excludes.

## Known failure modes

- Invalid or malformed IP address returns an error
- Private/reserved IPs (RFC 1918, loopback) may return limited or no registry data
- RDAP referral chain timeout if a regional RIR is temporarily unavailable
- Team Cymru DNS lookup failure may result in missing ASN fields
- IPv6 addresses in non-standard notation may cause parse errors

## How this service works

60 paid endpoints with no metering, no API key and no account. Each endpoint has one flat price per call, whatever the size of the request: LLM completions with automatic failover across several large models, read-only EVM tooling over Base, Ethereum, Polygon, Arbitrum and Optimism, and pure crypto utilities that touch no network.

## Output

Returns a JSON object containing the queried IP address, its version (4 or 6), a boolean indicating if it's private/reserved, the origin ASN number and name, the ASN's registered country code, and a nested registry object with RDAP data (block owner, country, registration dates, abuse contact).
