## 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 certaindata-ip-geolocation-2cdd5027
```

Example prompt: Can you look up the country, city, and network details for the IP address 203.0.113.47?

## When to prefer this

Use this endpoint when you need fast, per-IP geolocation enrichment including ASN/network data, city-level resolution, and subdivision details for both IPv4 and IPv6 addresses. Prefer this over free or unauthenticated alternatives when reliability and structured output with network context are required. Well-suited for fraud detection, analytics pipelines, or access control logic where you need to pay per lookup at low cost.

## Known failure modes

- Invalid IP address format returns a 400 or error response
- Private/reserved IP ranges (e.g. 192.168.x.x, 10.x.x.x) may return no location data
- Payment failure or missing x402 payment header returns 402 Payment Required
- Unknown or unroutable IP addresses may return partial or empty location fields
- Rate limiting may occur for high-frequency requests

## How this service works

Country, city, subdivisions, network (ASN), and approximate location for an IPv4 or IPv6 address.

## Output

Returns structured geolocation data for the queried IP address including country name and ISO codes, city, administrative subdivisions, ASN and network name, and approximate geographic coordinates.
