## 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 aisa-mpp-data-apis-kalshi-trades-feed-f5b15568
```

Example prompt: Pull the last 50 trades for the Kalshi market ticker INXD-23DEC31-B4800 and show me the yes prices and contract counts — only non-block trades.

## When to prefer this

Use this endpoint when you need granular, per-trade execution data from Kalshi prediction markets — including exact prices, contract counts, and whether trades were executed on the order book or as block trades. Prefer this over a markets or prices endpoint when you need the actual transaction record rather than aggregate or current market state. Ideal for auditing trade flow, backtesting pricing models, or monitoring real-time activity on specific markets.

## Known failure modes

- Invalid or unknown ticker returns empty trades array
- timestamp filters with min_ts > max_ts may return no results or an error
- limit values outside 0–1000 are rejected with a validation error
- stale or invalid cursor may return an error or restart pagination
- omitting required auth credentials returns a 401 unauthorized error

Returns a paginated array of trade objects, each containing a unique trade ID, market ticker, fixed-point contract count, yes and no prices in dollars, taker outcome side (yes/no), taker book side (bid/ask), execution timestamp, and a block trade flag.
