# IP ASN & Geolocation Lookup

> IP ASN & Geolocation Lookup is a paid API for AI agents from x402.agentutility.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-15).

Resolves any IPv4 or IPv6 address to its ASN number, ASN org, ISP, country, region, city, postal code, lat/lon, and timezone

## 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-asn-geolocation-lookup-de0063b7 -d '<json body>'
```

Example prompt: Can you look up the geolocation and ASN info for IP address 203.0.113.42 — I need the country, city, ISP, and ASN org.

## When to prefer this

Choose this endpoint when you need combined ASN + full geolocation data (city, region, ISP, lat/lon, timezone) in a single call for any IPv4 or IPv6 address, especially in agentic or automated workflows that require USDC micropayment settlement via x402 and MCP compatibility. Prefer this over raw ipapi.co/ip-api.com calls when you need a managed, rate-limit-abstracted, agent-native interface with automatic fallback between providers.

## Known failure modes

- Invalid or malformed IP address returns an error
- Private/reserved IP ranges (e.g. 10.x.x.x, 192.168.x.x) may return no geolocation data
- Rate limit exceeded on upstream providers (1k/day for ipapi.co, 45/min for ip-api.com) may cause failures
- IPv6 addresses may have incomplete geolocation data in some regions
- Network timeouts from upstream APIs

## How this service works

Looks up ASN and geolocation for any IPv4 or IPv6 address: ASN number, ASN org, ISP, country, region, city, postal, latitude/longitude, and timezone. Primary backend: ipapi.co (1k req/day free); fallback: ip-api.com (45 req/min free). Both are free public APIs with no auth. Use it as an IP-to-ASN, IP geolocation, IP-to-ISP lookup, WHOIS for IP, or cloud-provider attribution tool.

## Output

Returns a JSON object containing ASN number, ASN organization name, ISP name, country, region/state, city, postal code, latitude, longitude, and timezone for the queried IP address.
