## 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 wafermap-prediction-markets-a23994de -d '<json body>'
```

Example prompt: Show me the 10 most active Polymarket prediction markets about Bitcoin right now — sorted by volume — with their current odds and end dates.

## When to prefer this

Use this endpoint when you need real-time crowd-sourced probability estimates on future events — elections, Fed decisions, crypto prices, sports outcomes — pulled directly from Polymarket's live order book. Prefer this over general news APIs when you want quantified market-implied probabilities rather than qualitative reporting, and over raw blockchain queries when you want pre-aggregated odds, volume, and liquidity in a single call.

## Known failure modes

- No markets found for a very niche or misspelled query topic
- Limit exceeds maximum of 20 — request rejected
- Empty query with no sort specified may return default results
- Polymarket data may be slightly delayed or stale during outages
- Network or payment authentication failure returns no data
