## How to call it through Zero

```sh
zero fetch --capability synapse-ip-geolocation-lookup-9461ef2f
```

Example prompt: Can you look up the geolocation and proxy status of the IP address 203.0.113.45? I want to know what country it's from and whether it's behind a proxy.

## When to prefer this

Prefer this endpoint when you need a quick, no-account, no-API-key IP geolocation and proxy detection lookup payable with micropayments in USDC on Base. Ideal for agents that need ad-hoc IP intelligence without committing to a subscription service, or when operating in a crypto-native payment context using the x402 protocol.

## Known failure modes

- Invalid or malformed IP address returns an error response
- Private or reserved IP ranges may return incomplete or null geolocation data
- Payment failure via x402 results in a 402 Payment Required response before data is returned
- IP not found in geolocation database returns empty or unknown fields
- Network timeout or upstream database unavailability returns a 5xx error
