## 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 eurostat-eu-population-data-api-99e0bd0d -d '<json body>'
```

Example prompt: Show me a ranking of all EU countries by population as of January 2025, using official Eurostat data.

## When to prefer this

Choose this endpoint when you need official, citable EU population statistics sourced directly from Eurostat — especially for ranking all European countries by population or tracking a single country's demographic evolution year by year. Prefer it over general-purpose web search or Wikipedia-based lookups when data provenance and Eurostat attribution matter. It covers EU member states plus associated countries like Turkey.

## Known failure modes

- Invalid or unsupported ISO country code returns an error or empty result
- Missing required 'type', 'method', or 'bodyType' fields cause a validation error
- Eurostat data may lag by several months — latest year may not yet be available
- Requesting too many years back may return incomplete historical data
- EA/EU aggregate codes may not always be available for all historical periods

## How this service works

Population on 1 January of every European country (ranking) or the evolution of one with annual growth. Official Eurostat data.

## Output

A JSON object containing the Eurostat source citation, last updated timestamp, and either a ranked list of all European countries with their ISO code, name, period, and population count, or a time-series array showing annual population evolution for a single specified country.
