## 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 lukka-prediction-markets-pmcs-stats-9c083bc1
```

Example prompt: Pull up the latest prediction market stats from Lukka — I want to see how many contracts are active across each category like sports, and how they break down by exchange like Kalshi and Polymarket.

## When to prefer this

Use this endpoint when you need a high-level statistical snapshot of prediction market contract volumes broken down by category and exchange. Prefer this over individual market lookup endpoints when the goal is dashboard-style aggregation or comparative analysis across platforms like Kalshi and Polymarket.

## Known failure modes

- Invalid or malformed properties filter returns 400 error
- Endpoint temporarily unavailable returns 503
- Payment not processed (x402 payment required) returns 402
- Empty or stale data if markets have not updated recently

## How this service works
