## 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-attest-ip-lookup-0d499f50 -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, city, and ISP it belongs to.

## When to prefer this

Choose this endpoint when you need frictionless, pay-per-use IP geolocation with no API key or account setup — ideal for agents or workflows that handle sporadic IP lookups and want to pay only for what they use via x402 micropayments in USDC. Prefer this over subscription-based IP lookup services when call volume is low or unpredictable.

## Known failure modes

- Invalid IP address format returns an error
- Private or reserved IP ranges may return no geolocation data
- Payment failure via x402 results in a 402 response and no data returned
- Malformed request body missing the ip field causes a validation error
- IPv6 addresses may have less granular geolocation coverage

## 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 submitted IP address, likely including country, region, city, ISP, and ASN details. The response is returned directly after a successful micropayment of $0.002 USDC via x402 on Base or Solana.
