## 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 clinkagent-prediction-market-closing-soon-feed-fd5c6ec1
```

Example prompt: Show me the top 20 prediction markets on Polymarket and Kalshi closing in the next 24 hours, sorted by volume — I want to know which ones are settling today and how many hours I have left.

## When to prefer this

Use this endpoint when you need a cross-platform, volume-ranked snapshot of prediction markets approaching resolution — especially for deadline tracking, event-risk calendars, or trading urgency signals. Prefer it over manual Polymarket/Kalshi browsing when you want both platforms combined in one call with hours-to-close metadata.

## Known failure modes

- Invalid window value (not '24h' or '7d') returns a validation error
- limit out of range (below 1 or above 50) may return an error or be clamped
- no markets found for the given topic filter returns an empty list
- downstream Polymarket or Kalshi data unavailability may return stale or partial results
- payment failure (x402) if USDC balance is insufficient

## How this service works

Prediction markets closing soon - every market on Polymarket AND Kalshi settling within the next 24 hours or 7 days, sorted by volume, with hours-to-close. Event-risk calendars, deadline tracking, what resolves today. ?window=24h|7d&limit=1-50&q=<optional topic filter>.

## Output

A sorted list of prediction market entries from Polymarket and Kalshi, each including the market name/question, platform source, hours remaining until close, settlement deadline, and trading volume — filtered by the requested time window and optional topic query, limited to the specified count.
