Add AI-powered IP reputation analysis using Cloudflare Workers AI (Llama 3.1 70B)

[Copilot]

Integrates Cloudflare Workers AI to generate intelligent risk assessments for IP addresses using the Llama 3.1 70B Instruct model, analyzing real-time data from AbuseIPDB and Cloudflare Radar APIs.

Changes

Worker Configuration

• wrangler.toml: Added AI binding for Workers AI access

Worker Implementation

• cloudflare-worker.template.js:
  • New generateAIReputation() function calls Llama 3.1 70B with structured prompt
  • Analyzes abuse scores, report counts, ISP, country, and ASN data
  • Returns risk level (low/medium/high/critical), trust score (0-100), summary, and recommendations
  • Runs sequentially after parallel AbuseIPDB/Radar calls complete
  • Graceful degradation on AI service failures
  • Updated event handlers to pass env parameter for binding access

Service Models

• AbuseIPDBService.cs:
  • New AIReputation class with success, error, analysis, model, and timestamp fields
  • New AIAnalysis class with risk level, trust score, summary, and recommendations
  • Updated AbuseIPDBApiResponse to include AIReputation field

Response Format

{
  "data": { /* AbuseIPDB data */ },
  "asnInfo": { /* Cloudflare Radar ASN data */ },
  "aiReputation": {
    "success": true,
    "analysis": {
      "riskLevel": "medium",
      "trustScore": 65,
      "summary": "IP from US datacenter with 15 abuse reports. Moderate risk profile.",
      "recommendations": [
        "Review abuse report patterns",
        "Consider rate limiting for API access"
      ]
    },
    "model": "@cf/meta/llama-3.1-70b-instruct",
    "timestamp": "2025-10-28T04:45:00.000Z"
  }
}

Notes

• Maintains backward compatibility; existing response structure unchanged
• AI failures don't break worker; returns success: false with error message
• Temperature set to 0.3 for consistent factual responses
• All 41 existing tests pass; no regressions
