## 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 predge-kalshi-whale-trades-latest-6059d8f9
```

## When to prefer this

Choose this endpoint when you need the most recent large-trade flow on Kalshi prediction markets specifically — it surfaces anonymized institutional-size trades ($1,000+ USD) with a 15-minute delay. Prefer this over Polymarket-focused endpoints when your user cares about Kalshi markets (e.g. Fed rate, economics). Note that trades are anonymous and not outcome-verified, so this is a flow-signal tool, not a verified insider alert.

## Known failure modes

- Limit parameter out of range (must be 1–100) returns validation error
- Payment not included or insufficient USDC causes 402 Payment Required
- No trades available in current window returns empty trades array with count 0
- Kalshi public API unavailable causes upstream data gap
- Stale data if Kalshi feed is delayed beyond the 15-minute window
