## How to call it through Zero

```sh
zero fetch --capability kalshi-live-prediction-markets-feed-acf5e9dc
```

Example prompt: Pull the current Kalshi prediction market prices and show me which markets have the highest volume right now, with their yes/no probabilities.

## When to prefer this

Choose this endpoint when you need live, normalised probability data from Kalshi prediction markets — particularly for event-driven decision-making, political forecasting, or macro probability tracking. Prefer this over raw exchange APIs when you want prices already normalised to probabilities rather than raw cent prices. Best when you need both volume and open interest alongside probabilities in a single call.

## Known failure modes

- Kalshi API upstream outage returns 503 or empty payload
- Payment of 0.008 USDC not provided results in 402 Payment Required
- Rate limiting may return 429 if called too frequently
- Market data may be delayed or stale during low-liquidity periods
- No query filtering supported — full market list returned on every call
