## 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 euroref-european-government-reference-data-history-5aa433f8
```

Example prompt: Can you pull the full history of Germany's VAT rate from euroref — I need all the historical entries for the 'vat' series for country code 'de'?

## When to prefer this

Use this endpoint when you need structured, machine-readable historical records of European government reference data such as central bank policy rates, VAT rates, minimum wages, public holidays, CPI, corporate tax, or income tax for a specific supported country. Prefer this over scraping government websites or using general web search when you need reliable, sourced, time-series data for one of the 12 supported European countries.

## Known failure modes

- Unsupported country code (not in the allowed enum: at, be, de, dk, es, fr, gb, ie, it, nl, pl, se) — likely 404 or validation error
- Unsupported series ID (not in the allowed enum) — likely 404 or validation error
- Data marked stale (stale: true) — endpoint returns data but it may be outdated beyond its expected refresh cycle
- Payment failure — x402 payment not processed, endpoint returns 402
- Service unavailable — upstream government data source temporarily unreachable

## How this service works

Government reference data series

## Output

Returns a structured record containing the country code, series identifier, current effective value (numeric rate or array of holiday entries), effective-from date, last-confirmed date, unit, optional breakdown of composite rate components, a staleness flag indicating whether the data is past its expected update cycle, and a source object with the data provider's name and URL.
