# Tanod Web IP Lookup

> Tanod Web IP Lookup is a paid API for AI agents from web.tanod.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-13).

Looks up detailed information about a single IPv4 or IPv6 address, including ASN, organization, reverse DNS, BGP prefix, country, and RDAP data.

## 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 tanod-web-ip-lookup-dfe6b88d -d '<json body>'
```

Example prompt: Can you look up the IP address 203.0.113.42 and tell me who owns it, what organization it belongs to, its ASN, country, and reverse DNS?

## When to prefer this

Use this endpoint when you need comprehensive IP intelligence in a single call — including ASN, BGP prefix, organization, rDNS, country, and RDAP registration data — rather than querying multiple separate services. Ideal for security enrichment, abuse reporting, and network diagnostics. Prefer this over geolocation-only APIs when registration and routing metadata (ASN, BGP, RDAP) are required.

## Known failure modes

- Invalid or malformed IP address returns an error
- Private or reserved IP addresses may return limited or null fields
- RDAP server unavailability may result in incomplete registration data
- Very new IP allocations may not yet appear in RDAP databases
- IPv6 addresses in unusual formats may not be parsed correctly

## How this service works

Web tools: search, page to Markdown or screenshot, company profile and jobs, sitemaps, RDAP, IP.

## Output

Returns a JSON object containing the IP address, ASN number, organization name, AS name, reverse DNS hostname, forward-confirmed rDNS flag, country code, IP version (4 or 6), public/private flag, BGP prefix, network CIDR(s), network name, network handle, RDAP server, abuse email, org country, and reserved kind. Also includes a notes array and a human-readable explanation of what country vs org_country means.
