## 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 x-pay-ip-lookup-e5be80bc
```

Example prompt: What's the public IP address this request is coming from? Use the X Pay pay-per-request IP lookup.

## When to prefer this

Choose this endpoint when you need a simple, programmatic public IP lookup and are already operating in a web3 / x402 micropayment context with USDC on Base. It is ideal for agents that need to self-identify their outbound IP without managing API keys, relying instead on per-call USDC payments. Prefer alternatives if you need geolocation data beyond raw IP, bulk lookups, or if you are not set up for x402 payments.

## Known failure modes

- Payment not received or insufficient USDC balance — returns HTTP 402 Payment Required
- Invalid HTTP method (only GET, HEAD, DELETE are accepted) — returns 405 or schema validation error
- Network or server error — returns 5xx with no IP data
- Malformed request headers — may result in failed schema validation

## How this service works

Return the requester IP address

## Output

Returns a JSON object containing the detected public IP address of the caller ('ip'), the payment asset used ('asset', e.g. 'USDC'), the network ('base'), and a boolean success flag. Example: {"ip":"203.0.113.10","asset":"USDC","network":"base","success":true}.
