## How to call it through Zero

```sh
zero fetch --capability polymarket-prediction-market-movers-36791440
```

Example prompt: What are the 10 biggest probability movers on Polymarket in the last 24 hours — show me what spiked and what crashed, with current odds and volume.

## When to prefer this

Use this endpoint when you need to identify which prediction markets moved most significantly over a defined recent time window — ideal for breaking-news detection, event monitoring, or scanning for high-signal probability changes. It filters for liquid markets only (liquidity >= $5k, 24h volume >= $1k), so results are meaningful rather than noise. Prefer this over a general search endpoint when you want ranked movers rather than a specific market query.

## Known failure modes

- Invalid window parameter (only '24h' or '7d' accepted)
- Limit out of range (must be 1-50)
- No markets meeting liquidity thresholds ($5k liquidity, $1k 24h volume) found
- Upstream Polymarket data unavailable or stale
- Rate limiting or payment failure via x402 protocol

## How this service works

Prediction market movers - the biggest probability swings in the last 24h or 7d across liquid Polymarket markets (liquidity >= $5k, 24h volume >= $1k), up and down, with current probability, move in points, volume, and URL. Breaking-news detection, event monitoring, what changed today. ?window=24h|7d&limit=<1-50>.

## Output

A JSON object containing an array of market movers, each with the market question, probability move in points (positive = up, negative = down), current probability, 24h volume, and market URL. Also includes the requested time window and a universe summary showing how many eligible and total markets were scanned.
