## 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-changes-feed-european-government-reference-data-c0c53ac6
```

Example prompt: Tell me which euroref series for Germany or France have changed since January 1, 2026 — I need to know if the ECB policy rate, VAT rates, or minimum wages have been updated.

## When to prefer this

Use this endpoint when you need to detect what has changed in European government reference data since a specific date, rather than fetching the current value of a single series. It is ideal for polling workflows, compliance monitoring pipelines, or cache-invalidation logic where you want a compact diff of all changed series across countries rather than querying each series individually.

## Known failure modes

- Invalid or future 'since' date returns an empty changes array or 400 error
- Unsupported country code returns no results or an error
- Stale data flagged via staleness indicator but still returned
- Payment not received results in 402 response requiring x402 micropayment
- Network timeout if upstream government source is unavailable

## How this service works

Authoritative European government reference values as clean JSON: central-bank policy rates, VAT rates, national minimum wages and public holidays for Germany (de), France (fr). Every value carries a citation to its official primary source (government gazette or central-bank statement), an effective date, a last-confirmed date and a staleness flag.

## Output

A JSON object containing a 'since' date and a 'changes' array, where each item lists the series name (e.g. 'minimum-wage', 'vat-rate', 'policy-rate', 'public-holidays'), the country code (de or fr), and the effective date of the change. Each changed record traces back to an official primary source citation.
