# External API Integrations

#### Kaito AI Integration

Kaito AI provides advanced social intelligence and sentiment analysis for cryptocurrency projects. The integration enables real-time monitoring of social sentiment, trending topics, and market manipulation detection.

**Setup and Authentication**

**API Configuration**

```javascript
const KaitoClient = require('@kaito/api-client');

const kaitoConfig = {
  apiKey: process.env.KAITO_API_KEY,
  baseURL: 'https://api.kaito.ai/v1',
  timeout: 30000,
  retryAttempts: 3,
  rateLimitWindow: 60000, // 1 minute
  maxRequestsPerWindow: 100
};

const kaito = new KaitoClient(kaitoConfig);
```

**Authentication Setup**

```bash
# Environment variables
export KAITO_API_KEY="your_kaito_api_key_here"
export KAITO_WEBHOOK_SECRET="your_webhook_secret"
export KAITO_RATE_LIMIT="100" # requests per minute
```

**Core Integration Methods**

**Social Sentiment Analysis**

```javascript
class KaitoIntegration {
  async getSocialSentiment(tokenAddress, timeframe = '24h') {
    try {
      const response = await kaito.social.getSentiment({
        token: tokenAddress,
        timeframe: timeframe,
        sources: ['twitter', 'reddit', 'telegram', 'discord'],
        includeMetrics: true
      });

      return {
        overallSentiment: response.sentiment.overall,
        sentimentScore: response.sentiment.score, // -1 to 1
        confidence: response.confidence,
        volume: response.metrics.mentionVolume,
        engagement: response.metrics.engagementRate,
        influencerActivity: response.influencers.activity,
        manipulationFlags: response.flags.manipulation
      };
    } catch (error) {
      throw new Error(`Kaito sentiment analysis failed: ${error.message}`);
    }
  }

  async getTrendingTopics(category = 'defi') {
    const trending = await kaito.trends.getTopics({
      category: category,
      limit: 50,
      timeframe: '1h',
      includeMetrics: true
    });

    return trending.map(topic => ({
      keyword: topic.keyword,
      volume: topic.volume,
      sentiment: topic.sentiment,
      growth: topic.growthRate,
      relatedTokens: topic.tokens
    }));
  }

  async detectManipulation(tokenAddress) {
    const manipulation = await kaito.analysis.detectManipulation({
      token: tokenAddress,
      analysisDepth: 'comprehensive',
      timeframe: '7d'
    });

    return {
      manipulationScore: manipulation.score, // 0-100
      indicators: manipulation.indicators,
      patterns: manipulation.patterns,
      confidence: manipulation.confidence,
      recommendations: manipulation.recommendations
    };
  }
}
```

**Error Handling and Rate Limiting**

**Rate Limit Management**

```javascript
class KaitoRateLimiter {
  constructor(maxRequests = 100, windowMs = 60000) {
    this.maxRequests = maxRequests;
    this.windowMs = windowMs;
    this.requests = [];
  }

  async checkRateLimit() {
    const now = Date.now();
    this.requests = this.requests.filter(time => now - time < this.windowMs);
    
    if (this.requests.length >= this.maxRequests) {
      const oldestRequest = Math.min(...this.requests);
      const waitTime = this.windowMs - (now - oldestRequest);
      await this.sleep(waitTime);
    }
    
    this.requests.push(now);
  }

  sleep(ms) {
    return new Promise(resolve => setTimeout(resolve, ms));
  }
}
```
