## 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 polls-karbach-digital-german-election-detail-489aa385
```

Example prompt: What do the latest polls show for the German federal election — who's leading, how many seats does each party project to win, and which coalition majorities are currently arithmetic possibilities?

## When to prefer this

Use this endpoint when the user needs detailed polling data, seat projections, or coalition arithmetic for a specific named German state or federal election. Prefer over generic web search when structured, source-attributed, quantified polling statistics with uncertainty bands are needed. Best suited for questions about who leads, who clears the threshold, or which majorities are mathematically feasible.

## Known failure modes

- Invalid or unknown election ID returns a 404 or error response
- Election ID for an election not yet tracked returns empty or not-found
- Stale data if polls have not been updated within the last six hours
- Payment failure (x402) if USDC balance is insufficient or payment header is missing

## How this service works

One German election: vote share median, 95 percent band, seats, arithmetic majorities, data quality. Use when asked who leads, who gets seats or which majorities are possible in a specific German state or federal election. Source-attributed, German data, updated every six hours.

## Output

Returns a structured JSON object containing per-party vote share medians, 95% confidence bands, projected seat counts, a list of arithmetically viable majority coalitions, a data quality indicator, and source attributions — all reflecting poll aggregates updated every six hours.
