## 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 adh-kalshi-prediction-market-odds-0f4f09ba
```

Example prompt: Pull the latest Kalshi prediction market odds for all macro economic and crypto events — I want to see the yes/no probabilities and volumes so I can cross-check them against Polymarket for any pricing divergences.

## When to prefer this

Choose this endpoint when you need CFTC-regulated, compliance-grade prediction market probabilities for macro-economic, crypto, climate, or technology events without requiring a Kalshi API key. Prefer over Polymarket when regulatory compliance and US market data are priorities, or use alongside Polymarket for cross-validation and arbitrage detection. Ideal for enriching AI agent financial context with crowd-sourced probability estimates on forward-looking macro events.

## Known failure modes

- Kalshi public API unavailable or rate-limited — upstream source error
- Stale data if collection_at timestamp is significantly behind current time
- No markets returned if Kalshi changes its public endpoint structure
- x402 payment failure if USDC balance insufficient
- Empty data array if all markets filtered out by category rules
