## 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 tollkit-ip-lookup-701e0c9a -d '<json body>'
```

Example prompt: Look up the geolocation and network info for IP address 203.0.113.42 — I want to know what country and city it's in and who the ISP is.

## When to prefer this

Choose this endpoint when you need instant, no-signup IP geolocation or network metadata and want to pay per-call with USDC via x402 rather than managing API subscriptions. Ideal for agents that need occasional IP lookups without committing to a monthly plan, or for serverless workflows where credential management is a burden.

## 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 useful geolocation data
- Payment failure via x402 (insufficient funds, unsupported network) results in 402 response
- Endpoint unavailable or rate-limited returns 5xx error
- IPv6 addresses may have less precise geolocation data

## How this service works

Pay-per-call product page extraction. No account, no API key: pay in-band with x402 in USDC on Base or Solana.

## Output

Returns geolocation and network metadata for the queried IP address, likely including country, region, city, ISP/organization, and possibly ASN or coordinates. Payment is processed inline via x402 at $0.002 USDC per call with no account or API key needed.
