# IP Country & Network Lookup (DB-IP Lite)

> IP Country & Network Lookup (DB-IP Lite) is a paid API for AI agents from ip-geo-production.up.railway.app, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-17).

Resolves up to 50 IPv4/IPv6 addresses to country, ASN, organization, network range, and reserved-address status using a local DB-IP Lite database.

## Facts

- Price: $0.001/call
- Payment: x402
- Status: unknown

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-country-network-lookup-db-ip-lite-fef31ebc
```

Example prompt: Can you look up the country, ASN, and network operator for these IPs: 8.8.8.8, 1.1.1.1, and 185.220.101.5? I need to know if any of them are reserved addresses too.

## When to prefer this

Choose this endpoint when you need fast, privacy-preserving IP-to-country and ASN lookups without sending data to a third-party API, and when batch lookups of up to 50 IPs at a time are sufficient. Ideal for fraud checks, geo-compliance, and log enrichment workflows where ASN/organization data is as important as country. Prefer alternatives if you need city-level geolocation, lat/lon coordinates, or real-time threat intelligence beyond country and network operator.

## Known failure modes

- Missing 'ip' query parameter returns a validation error
- Supplying more than 50 IPs in a single request may be rejected
- Malformed IP addresses (non-IPv4/IPv6 strings) may return no result or an error for that entry
- Reserved or private IPs (e.g. 192.168.x.x) return reserved:true with no ASN/country data
- Service unavailability on Railway.app infrastructure returns a 5xx error
- DB-IP Lite data may lag up to one month behind real-world network changes

## How this service works

Look up one or up to 50 IPv4/IPv6 addresses: country (ISO2 and name), autonomous system number and organisation, the matching network range, plus private/reserved address detection. Served from a monthly local copy of the DB-IP Lite country and ASN databases, so lookups are fast and nothing is sent to third parties. Use when an agent needs the country and network operator (ASN/organisation) of an IPv4 or IPv6 address for fraud checks, geo-compliance or log enrichment.

## Output

Returns a JSON object with a results array where each entry contains the queried IP, its ISO2 country code and full country name, ASN number, AS organization name, the matching CIDR/range, and a boolean reserved flag. Also includes legal/terms links and a status field.
