## 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 prediction-trending-0e31169e
```

Example prompt: Show me the top 15 trending prediction markets on Polymarket right now, including their 24-hour volume, total volume, and liquidity.

## When to prefer this

Use this endpoint when you need a ranked, ready-to-consume summary of the most actively traded prediction market events by 24-hour volume, specifically on Polymarket. Prefer this over building your own Polymarket scraper or using raw market APIs when you want normalized volume, liquidity, and metadata in a single call. Ideal for daily briefings, market monitoring agents, or identifying where speculative interest is concentrated.

## Known failure modes

- Invalid limit value (outside 1–25 range) returns a validation error
- Unsupported venue value returns an enum validation error
- No trending events found may return an empty list
- Downstream Polymarket data unavailability may cause stale or empty results
- Rate limiting or payment failure (x402) may block access
