## 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 quantaflow-ip-geolocation-api-x402-2506178a -d '<json body>'
```

Example prompt: Look up the geolocation details for IP address 8.8.8.8 — I need the country, city, region, ISP, and timezone.

## When to prefer this

Choose this endpoint when you need IP geolocation data and want to pay per-query via x402 USDC micropayments without a subscription or API key, especially in web3-native or agent-based workflows where on-chain micropayments are preferred over traditional billing.

## Known failure modes

- Invalid or private IP address returns an error or empty result from upstream
- Payment failure or insufficient USDC balance results in 402 Payment Required with no data returned
- Malformed request path or query parameters may cause upstream to return a fail status
- Rate limiting by the upstream ip-api.com service may result in throttled or blocked responses
- Network timeout from the upstream provider returns no geolocation data

## How this service works

## Output

Returns the upstream ip-api.com response body containing geolocation fields such as country, countryCode, region, city, zip, latitude, longitude, timezone, ISP, organization, and AS number for the queried IP address.
