## 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-markets-data-via-proxy-suverse-io-500f8dae -d '<json body>'
```

Example prompt: Pull the current list of Kalshi prediction markets and show me the tickers, yes/no bid and ask prices, last traded price, volume, and open interest for each one.

## When to prefer this

Use this endpoint when you need structured, machine-readable access to Kalshi prediction market data — including prices, volume, and open interest — without managing your own Kalshi API credentials. It is ideal for agents that need real-time event-contract data from the US-regulated Kalshi exchange on a pay-per-call basis via x402 micropayments.

## Known failure modes

- Kalshi upstream API unavailable — proxy returns 5xx error
- Rate limiting or quota exceeded — returns 429 or payment-related error
- Empty response if no markets are currently active
- Stale data if Kalshi API is lagging behind real-time
- x402 payment not processed — returns 402 Payment Required
