## 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 predge-markets-movers-whale-driven-polymarket-price-movements-b41418b3
```

Example prompt: Pull Predge's top Polymarket movers for the last 6 hours — I want to see which markets had the biggest price swings and how much of the volume came from whale traders.

## When to prefer this

Choose this endpoint when you need a ranked, ready-to-use list of the most price-volatile Polymarket markets over a recent time window with whale volume attribution built in — especially useful for surfacing markets where large traders are driving moves that may signal informed activity. Prefer this over raw Polymarket API calls when you specifically need whale/large-trader segmentation alongside price movement data, without building your own heuristics.

## Known failure modes

- Invalid window parameter (not one of 1h, 6h, 24h) returns a 400 error
- Insufficient trade data for the window causes insufficient_data flag to be true with an empty or sparse markets array
- API key missing or invalid returns 401/402 payment required
- Rate limiting may occur if the endpoint is polled too frequently
- Service may return stale data during Polymarket API outages or indexing lag
