# IP Lookup – Geolocation, ASN, ISP & Proxy Status

> IP Lookup – Geolocation, ASN, ISP & Proxy Status is a paid API for AI agents from ipx402.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-15).

Resolves an IPv4 or IPv6 address to its geolocation, ASN, ISP, and proxy/VPN status

## Facts

- Endpoint: GET https://ipx402.com/v1/ip
- Price: $0.01/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/ip-lookup-geolocation-asn-isp-proxy-status-94597e53
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_0WTy_x-pHDn2pQstBw4BM

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-lookup-geolocation-asn-isp-proxy-status-94597e53
```

Example prompt: Can you look up the IP address 203.0.113.42 and tell me what country it's from, who the ISP is, and whether it's a known proxy or VPN?

## When to prefer this

Choose this endpoint when you need a single-call resolution of an IP address into geolocation plus network metadata (ASN, ISP) plus proxy/VPN detection in one response. It covers both IPv4 and IPv6 and returns structured JSON ready for downstream use. Prefer this over raw WHOIS lookups when you need city-level geo data and proxy flagging combined, or over pure geo APIs when ISP and ASN context also matter.

## Known failure modes

- Invalid or malformed IP address returns success: false with no geolocation data
- Private/reserved IP ranges (e.g. 192.168.x.x) may return valid: false or empty geolocation
- Unknown or unallocated IPs may return partial data with missing city/region fields
- Network timeout or upstream service unavailability returns a non-200 code field
- Payment failure (insufficient USDC balance) blocks the request before it reaches the lookup service

## How this service works

Geolocation, ASN, proxy and threat intelligence for any IP address.

## Output

Returns a JSON object with the IP's validity flag, city, region, country, ISO alpha-2 country code, latitude, longitude, zip code, timezone, ASN, ISP name, IP version, a boolean is_proxy flag, and when applicable a proxy sub-object with proxy type, domain, city, and country.
