## 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 beggar-bot-kalshi-market-endpoint-04854037
```

Example prompt: Can you pull the current Kalshi prediction market data so I can see what markets are available and their current odds?

## When to prefer this

Use this endpoint when you need live Kalshi prediction market data and are operating in an x402-enabled agent environment that can pay $0.02 USDC on Base mainnet. Prefer this over scraping Kalshi directly when you need a structured JSON API response with micropayment support baked in. Best for agents that already have USDC on Base and need quick programmatic access to Kalshi market listings.

## Known failure modes

- Payment not provided or insufficient — returns HTTP 402 requiring USDC payment on Base mainnet
- Invalid or malformed properties filter parameter — returns error or empty results
- Kalshi upstream API unavailable — may return 502 or error JSON
- Network parameter misconfigured — defaults to base mainnet but may fail on unsupported networks
- Rate limiting or worker timeout on Cloudflare — returns 429 or 503
