## 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 x402-kalshi-market-detail-6036e35b
```

Example prompt: What are the current yes and no bid/ask prices, volume, and status for the Kalshi market with ticker KXELONMARS-99?

## When to prefer this

Use this endpoint when you need comprehensive details about a specific Kalshi market by ticker — including bid/ask spreads, volume, timestamps, and resolution result — as opposed to just browsing available markets. Prefer this over generic prediction market aggregators when you already have the Kalshi ticker and need structured, machine-readable data suitable for agent decision-making or trading logic.

## Known failure modes

- Missing or invalid ticker returns an error — ticker must be a valid Kalshi market identifier obtainable from the /api/kalshi-markets endpoint
- Market not found if ticker is misspelled or does not exist
- Payment failure if insufficient USDC balance for the $0.002 per-call fee
- Network or upstream Kalshi API outage resulting in unavailable data
