# Polymarket Comprehensive Skill

Complete assistance with Polymarket development - covering the full platform (API, trading, market data) and the real-time data streaming client (WebSocket subscriptions for live market activity).

## When to Use This Skill

This skill should be triggered when:

**Platform & API:**
- Working with Polymarket prediction markets
- Using Polymarket API for market data
- Implementing trading strategies
- Building applications with Polymarket services
- Learning Polymarket best practices

**Real-Time Data Streaming:**
- Connecting to Polymarket's WebSocket service
- Building prediction market monitoring tools
- Processing live trades, orders, and market updates
- Monitoring market comments and social reactions
- Tracking RFQ (Request for Quote) activity
- Integrating crypto price feeds

## Quick Reference

### Real-Time Data Client Setup

**Installation:**
```bash
npm install @polymarket/real-time-data-client
```

**Basic Usage:**
```typescript
import { RealTimeDataClient } from "@polymarket/real-time-data-client";

const onMessage = (message: Message): void => {
    console.log(message.topic, message.type, message.payload);
};

const onConnect = (client: RealTimeDataClient): void => {
    client.subscribe({
        subscriptions: [{
            topic: "activity",
            type: "trades"
        }]
    });
};

new RealTimeDataClient({ onMessage, onConnect }).connect();
```

### Supported WebSocket Topics

**1. Activity (`activity`)**
- `trades` - Completed trades
- `orders_matched` - Order matching events
- Filters: `{"event_slug":"string"}` OR `{"market_slug":"string"}`

**2. Comments (`comments`)**
- `comment_created`, `comment_removed`
- `reaction_created`, `reaction_removed`
- Filters: `{"parentEntityID":number,"parentEntityType":"Event"}`

**3. RFQ (`rfq`)**
- Request/Quote lifecycle events
- No filters, no auth required

**4. Crypto Prices (`crypto_prices`, `crypto_prices_chainlink`)**
- `update` - Real-time price feeds
- Filters: `{"symbol":"BTC"}` (optional)

**5. CLOB User (`clob_user`)** ⚠️ Requires Auth
- `order` - User's order updates
- `trade` - User's trade executions

**6. CLOB Market (`clob_market`)**
- `price_change` - Price movements
- `agg_orderbook` - Aggregated order book
- `last_trade_price` - Latest prices
- `market_created`, `market_resolved`

### Authentication for User Data

```typescript
client.subscribe({
    subscriptions: [{
        topic: "clob_user",
        type: "*",
        clob_auth: {
            key: "your-api-key",
            secret: "your-api-secret",
            passphrase: "your-passphrase"
        }
    }]
});
```

### Common Use Cases

**Monitor Specific Market:**
```typescript
client.subscribe({
    subscriptions: [{
        topic: "activity",
        type: "trades",
        filters: `{"market_slug":"btc-above-100k-2024"}`
    }]
});
```

**Track Multiple Markets:**
```typescript
client.subscribe({
    subscriptions: [{
        topic: "clob_market",
        type: "price_change",
        filters: `["100","101","102"]`
    }]
});
```

**Monitor Event Comments:**
```typescript
client.subscribe({
    subscriptions: [{
        topic: "comments",
        type: "*",
        filters: `{"parentEntityID":12345,"parentEntityType":"Event"}`
    }]
});
```

## Key Features

**Platform Capabilities:**
✅ Prediction market creation and resolution
✅ Trading API (REST & WebSocket)
✅ Market data queries
✅ User portfolio management
✅ Event and market discovery

**Real-Time Streaming:**
✅ WebSocket-based persistent connections
✅ Topic-based subscriptions
✅ Dynamic subscription management
✅ Filter support for targeted data
✅ User authentication for private data
✅ TypeScript with full type safety
✅ Initial data dumps on connection

## Best Practices

### WebSocket Connection Management
- Use `onConnect` callback for subscriptions
- Implement reconnection logic for production
- Clean up with `disconnect()` when done
- Handle authentication errors gracefully

### Subscription Strategy
- Use wildcards (`"*"`) sparingly
- Apply filters to reduce data volume
- Unsubscribe from unused streams
- Process messages asynchronously

### Performance
- Consider batching high-frequency data
- Use filters to minimize client processing
- Validate message payloads before use

## Requirements

- **Node.js**: 14+ recommended
- **TypeScript**: Optional but recommended
- **Package Manager**: npm or yarn

- **Real-Time Client Repo**: https://github.com/Polymarket/real-time-data-client
- **API Documentation**: See references/api.md

### Working with This Skill

**For Beginners:**
Start with `getting_started.md` for foundational concepts.

**For API Integration:**
Use `api.md` and `trading.md` for REST API details.

**For Real-Time Data:**
Use `README.md` for WebSocket client implementation.

**For LLM Integration:**
Use `llms.md` and `llms-full.md` for AI/ML use cases.

## Notes

- Real-Time Client is TypeScript/JavaScript (not Python)
- Some WebSocket topics require authentication
- Use filters to manage message volume effectively
- All timestamps are Unix timestamps
- Market IDs are strings (e.g., "100", "101")
- Platform documentation covers both REST API and WebSocket usage
