## 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-markets-movers-a2608108
```

Example prompt: Show me the top-moving Kalshi prediction markets over the last 6 hours, including which ones have the most whale institutional volume — I want to know where the big money is moving.

## When to prefer this

Use this endpoint when you specifically want to monitor price-moving Kalshi prediction markets and detect large institutional or whale flows in near real-time. Prefer it over generic Kalshi API access when you need pre-computed price deltas and volume breakdowns without building your own trade aggregation logic. Best suited for agents doing market surveillance, briefing generation, or anomaly detection on Kalshi.

## Known failure modes

- Insufficient trade data for the window returns insufficient_data: true with an empty markets array
- Invalid window value returns a validation error
- Kalshi public API downtime may cause stale or missing data
- Payment not included or insufficient USDC results in HTTP 402 with no data returned
