# 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
