## 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 kalshi-market-trades-feed-794906d7 -d '<json body>'
```

Example prompt: Pull the most recent executed trades for the Kalshi market with ticker PRES-2024-REP — I want to see price, contract count, taker side, and timestamp for each trade.

## When to prefer this

Use this endpoint when you need the real-time trade execution tape for a specific Kalshi prediction market, including directional taker-side data and per-trade timestamps. Prefer this over order book snapshots when you want to analyze actual executed volume and price discovery. It is the right choice for monitoring momentum, spotting large trades, or tracking how a contract's price has moved through recent fills on a US-regulated event market.

## Known failure modes

- Invalid or unknown ticker returns empty result or error
- Kalshi API rate limit or downtime causes upstream failure
- Malformed request body returns 400 or validation error
- Payment failure (x402) if USDC is not provided
- Ticker format case sensitivity may cause no-match
