## 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 saylor-innovations-prediction-markets-kalshi-event-detail-79945ec6
```

Example prompt: Pull up the full details for the Kalshi prediction market event KXPRESNOMD-28 — I want to see its title, platform, and all the associated market contracts.

## When to prefer this

Use this endpoint when you need structured detail on a specific Kalshi prediction market event by its ticker ID, including its markets and metadata. Prefer this over general Kalshi API access when you want a low-cost, agent-friendly proxy that handles authentication and returns a normalized JSON response.

## Known failure modes

- Event ID not found or expired — returns empty or error response
- Kalshi API downstream unavailable — service may return 5xx
- Invalid event ticker format — may return null or malformed response
- Market event has closed or been resolved — data may be stale or unavailable

## How this service works

Prediction Market Event Detail. Every market in one prediction-market event (Polymarket event slug or Kalshi event ticker) with implied probabilities, bid/ask, volume, liquidity and close time.

## Output

Returns a JSON object containing the event's platform (Kalshi), event ID, title, and an array of associated market objects with contract details for the specified prediction market event.
