Example prompt: Can you give me a full comparison of all 27 EU countries on unemployment, inflation, and household energy prices, including how each country's strongest party performed in the 2024 European Parliament election?

## When to prefer this

Choose this endpoint when you need a single-call, multi-dimensional comparison across all 27 EU countries covering economic indicators (unemployment, inflation) and energy prices alongside 2024 European election results. Prefer it over general-purpose data sources when you need source-attributed, regularly refreshed EU-specific data in one response without stitching together multiple Eurostat queries.

## Known failure modes

- Upstream Eurostat data temporarily unavailable — may return stale or partial data
- Rate limiting or payment failure if x402 micropayment is not correctly handled
- Service downtime returns 5xx HTTP error
- Partial data if one of the four indicator streams has not yet refreshed in the current 6-hour cycle
