## 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 pennyrail-locale-brief-counterparty-locale-lookup-65288401 -d '<json body>'
```

Example prompt: Can you pull up a brief locale profile for my counterparty so I know what jurisdiction they're in before I finalize this settlement?

## When to prefer this

Use this endpoint when you need a lightweight, machine-readable locale brief for a counterparty as part of a payment or settlement workflow — particularly when operating within the x402 micropayment ecosystem and you only need a compact locale summary rather than a full KYC or identity profile.

## Known failure modes

- Missing or malformed 'input' object returns a validation error
- Unrecognized counterparty identifier may return empty or null locale data
- Payment not included or insufficient USDC balance results in 402 Payment Required
- Server-side locale resolution failure returns a generic error response
- Network timeout or Vercel cold-start latency may cause transient failures
