## 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 mearef-country-brief-middle-east-reference-data-b3683f35
```

Example prompt: Pull up the full government reference brief for Saudi Arabia — I need the policy rate, VAT, corporate tax, CPI, minimum wage, and anything else Mearef has on file, with official sources and confidence labels.

## When to prefer this

Choose this endpoint when you need a single-call, citation-backed snapshot of all key government reference figures for one Middle Eastern country. It is preferable over individual series endpoints when you need multiple data points (e.g. both VAT and corporate tax) in the same request, saving latency and cost. It is also preferable over generic financial data APIs when you require official gazette citations, effective dates, and confidence labels rather than bare numeric values.

## Known failure modes

- Country code not in Middle East coverage scope — returns 404 or empty result
- Invalid or unrecognized ISO 3166-1 alpha-2 code — returns 400 bad request
- Data may be stale if last-confirmed date is old and confidence label is low — returned but flagged
- Payment not fulfilled (x402) — returns 402 Payment Required before data is delivered
- Transient upstream outage — returns 503 or timeout
