## 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-middle-eastern-emerging-market-government-reference-data-all-12ab8a81
```

Example prompt: Pull the full mearef snapshot — every country and every series — so I can check current VAT rates, CPI figures, and holiday calendars across all supported Middle Eastern countries at once.

## When to prefer this

Use this endpoint when you need a complete bulk snapshot of all available government reference series across all countries in a single call — ideal for populating compliance dashboards, seeding databases, or running cross-country comparisons. Prefer individual country/series endpoints (sibling endpoints) when you only need one country or one series to minimize cost and payload size. Prefer this all-series endpoint when you want to avoid making many separate calls.

## Known failure modes

- HTTP 402 Payment Required if x402 payment header is missing or invalid
- Empty or partial dataset if some country series are currently being updated
- Stale data flag set to true for series that have not been refreshed within their expected cycle
- Network timeout on large payload if connection is slow
- Malformed response if upstream official sources are temporarily unavailable

## How this service works

Snapshot of every series, all countries

## Output

A JSON array of country objects, each containing an array of series entries. Each series entry includes: ISO country code, series name, value (numeric rate or holiday array), effective_from date, last_confirmed date, stale boolean, source object (name + URL), optional unit, optional notes, optional rate components breakdown, and optional effective_rate for stacked levies. Stale entries are flagged when past their expected update cycle.
