Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```

Example prompt: What do the latest polls say about a 2027 French presidential runoff between Marine Le Pen and Jean-Luc Mélenchon — who's ahead and what's the win probability for each?

## When to prefer this

Use this endpoint when you need a source-attributed, aggregated poll average with win probabilities specifically for the 2027 French presidential election runoff (second round). It is preferred over raw poll scrapers because it provides already-computed win probabilities, cites its sources, and self-refuses when data is stale — making it safe for time-sensitive agent workflows.

## Known failure modes

- 503 Not Available: data is older than 30 hours — stale data is refused and not charged
- 503 Legal Blackout: request falls within the French legal polling blackout window (17–18 Apr or 1–2 May 2027)
- No matching pair: the requested candidate combination has not been polled or is not in the dataset
- Payment failure: x402 payment of $0.02 USDC not processed, request rejected

## How this service works

French presidential election 2027, runoff: head-to-head poll average and win probability per tested pair. Unavailable during the legal blackout (17 to 18 Apr and 1 to 2 May 2027). Use when asked how a French presidential runoff between two candidates would end. Source-attributed. Refused (503, not charged) if data is older than 30 hours.

## Output

Returns poll-aggregated head-to-head percentages for each candidate in the tested pair, along with a computed win probability per candidate, data source attribution, and a freshness indicator. Returns 503 if underlying data is older than 30 hours, and is unavailable (also 503) during the legal polling blackout periods (17–18 April and 1–2 May 2027).
