Overview

This PR adds complete OpenAI ChatGPT integration to the Web3AI repository, enabling AI-powered conversations with a focus on Web3 and blockchain technology. The integration follows security best practices and is optimized for OpenAI Pro accounts.

What's New

🤖 ChatGPT Service Module (chatgpt.js)

• ChatGPTService class with OpenAI SDK v6.1.0 integration
• Two interaction modes:
  • chat() - Complete responses with token usage tracking
  • streamChat() - Real-time streaming responses for better UX
• Customizable options:
  • Model selection (GPT-4, GPT-4-turbo, GPT-3.5-turbo)
  • Temperature control (creativity/determinism)
  • Token limits
  • Custom system prompts
• Default GPT-4 model for Pro account capabilities
• Web3/blockchain specialized default system prompt
• Robust error handling with informative messages

🚀 Demo Application (index.js)

Demonstrates three key use cases:

1. Simple Web3 question with default settings
2. Custom model parameters (temperature, max tokens)
3. Streaming response for real-time output

🔐 Security Implementation

• Environment variables for API key management using dotenv
• .env.example template with clear instructions
• .gitignore updated to exclude:
  • .env (protects API keys)
  • node_modules/ (dependencies)
  • Log files
• API key validation on service initialization
• Zero hardcoded credentials in source code

📖 Comprehensive Documentation

• Prerequisites (Node.js v18+, OpenAI API key)
• Step-by-step setup instructions
• API key acquisition guide with direct links
• Usage examples (simple, custom, streaming)
• API reference with parameter descriptions
• Security best practices prominently featured
• Model information and recommendations

Usage Example

import ChatGPTService from './chatgpt.js';

const chatGPT = new ChatGPTService();

// Simple chat
const response = await chatGPT.chat('What is Web3?');
console.log(response.message);

// Streaming response
const stream = await chatGPT.streamChat('Explain smart contracts');
for await (const chunk of stream) {
  process.stdout.write(chunk.choices[0]?.delta?.content || '');
}

Quick Start

npm install
cp .env.example .env
# Add your OpenAI API key to .env
npm start

Security Features

✅ API keys stored in environment variables only
✅ .env excluded from version control
✅ Validation prevents execution without API key
✅ Clear security warnings in documentation
✅ No sensitive data in committed code

Pro Account Optimization

• Default GPT-4 model for advanced capabilities
• Support for latest OpenAI features and models
• Optimized for higher rate limits
• Documentation highlights Pro account benefits

Files Changed

• Created: package.json, chatgpt.js, index.js, .env.example, INTEGRATION_SUMMARY.md
• Modified: README.md (comprehensive docs), .gitignore (security)

This integration provides a production-ready foundation for AI-powered Web3 applications with enterprise-grade security practices.
