## 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-order-book-via-proxy-suverse-io-14819f29 -d '<json body>'
```

Example prompt: Pull the live order book for the Kalshi market with ticker INXD-24DEC31-T4500 — I want to see the yes and no price levels and how much is resting at each level.

## When to prefer this

Use this endpoint when you need real-time order book depth (full price ladder and resting sizes) for a specific Kalshi prediction market, rather than just the top-of-book quoted price. Prefer this over general market summary endpoints when you need to assess liquidity, calculate market impact, or monitor spread changes.

## Known failure modes

- Invalid or unknown ticker returns an error or empty order book
- Market not currently active or trading halted may return empty levels
- Rate limits or proxy downtime may cause 5xx errors
- Stale data if Kalshi API is experiencing latency
- Malformed request body (wrong bodyType or missing fields) returns 400
