# IP ASN Geo Lookup

> IP ASN Geo Lookup is a paid API for AI agents from 164.160.90.241.sslip.io, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-12).

Looks up an IP address to return its ASN, organization, reverse hostname, city, region, country, coordinates, and timezone.

## Facts

- Endpoint: GET https://164.160.90.241.sslip.io/api/dev-ip-asn-bgp-lookup?utm_source=zero.xyz

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-geo-lookup-f89c5525
```

Example prompt: Can you look up the IP address 8.8.8.8 and tell me its ASN, organization, country, city, coordinates, and timezone?

## When to prefer this

Choose this endpoint when you need a combined ASN + geolocation + reverse hostname lookup in a single call, especially for cybersecurity enrichment, access log analysis, or network intelligence. Prefer it over pure geo APIs when BGP/ASN data is also needed, or over pure WHOIS when you need geographic coordinates and timezone rather than registration data.

## Known failure modes

- Invalid or malformed IP address returns an error response
- Private/reserved IP ranges (e.g. 192.168.x.x, 10.x.x.x) may return no geo data
- Localhost (127.0.0.1) or loopback addresses will not resolve to geo information
- Some IPs may lack full data (e.g. no reverse hostname or incomplete geo data)
- Payment failure or insufficient USDC balance results in a 402 response

## How this service works

IP address lookup: ASN and organisation, reverse hostname, city, region, country, coordinates and timezone.

## Output

Returns a JSON object containing the IP's ASN number, organization name, reverse DNS hostname, city, region, country, geographic coordinates (latitude/longitude), and timezone.
