+description: "查询Polymarket预测市场。用于关于预测市场、投注赔率、市场价格、事件概率的问题，或当用户询问Polymarket数据时使用。"
+---
+
+# Polymarket
+
+Query prediction market data from Polymarket's public API (no auth required).
+
+## Quick Start
+
+```bash
+# Top markets by 24h volume
+python3 scripts/polymarket.py --top
+
+# Search markets
+python3 scripts/polymarket.py --search "trump"
+
+# Get specific market by slug
+python3 scripts/polymarket.py --slug "will-trump-win-the-2024-election"
+
+# List events (grouped markets)
+python3 scripts/polymarket.py --events
+```
+
+## Script Location
+
+`skills/polymarket/scripts/polymarket.py`
+
+## API Endpoints
+
+The script uses `gamma-api.polymarket.com`:
+- `/markets` - Individual markets with prices, volumes
+- `/events` - Event groups containing related markets
+
+## Output Format
+
+Markets show: question, Yes/No prices (as percentages), 24h volume, total volume.
+
+## Interpreting Prices
+
+- `outcomePrices` are 0-1 representing probability
+- Price of 0.65 for "Yes" = market thinks 65% chance of Yes
+- Higher volume = more liquid, more reliable signal
