## 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-agentutility-ai-c5118390 -d '<json body>'
```

Example prompt: Pull all active Kalshi markets related to Federal Reserve rate decisions with at least 500 contracts of volume and show me the prices as probabilities so I can compare them across venues.

## When to prefer this

Use this endpoint when you need live, CFTC-regulated prediction market data from Kalshi specifically, especially when you want prices already normalized to 0–1 probabilities for easy cross-venue comparison. Prefer this over scraping Kalshi directly or using general financial data APIs when the goal is event contract discovery and probability lookup without order entry.

## Known failure modes

- Kalshi upstream API unavailable — returns error or empty list
- Invalid series or event ticker — returns empty result set
- No markets match filter criteria — returns empty array
- Minimum volume filter too high — returns fewer or zero results
- Payment failure (x402 USDC) — request not processed
