## 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 sixpath-asn-lookup-449b9e1c -d '<json body>'
```

Example prompt: Can you look up the ASN information for the IP address 203.0.113.42 and tell me which organization and network it belongs to?

## When to prefer this

Use this endpoint when you need quick, pay-per-call ASN and network ownership lookups without a subscription commitment. Suitable for agents performing ad-hoc IP intelligence enrichment, cybersecurity investigations, or network diagnostics where cost-per-query via USDC on Base chain is acceptable.

## Known failure modes

- Invalid or malformed IP address returns an error
- Private/reserved IP ranges (e.g. 192.168.x.x) may return no ASN data
- ASN not found for edge-case or unallocated IP blocks
- Network timeout or upstream data source unavailability
- Missing required input field returns 400 error
- Payment failure via x402 protocol prevents request from being processed

## How this service works

All-in-one API hub: Social Media, Jobs, Finance, Crypto, and Tools. Pay-per-call with x402 protocol on Base chain.

## Output

Returns ASN metadata including the ASN number, owning organization or ISP name, network CIDR range, country of registration, and routing details associated with the queried IP address or ASN.
