conversation = response.json()

# Send message with AI tools
response = requests.post(
    'http://localhost:5000/api/chat',
    json={
        'message': 'Latest iPhone 15 price in India',
        'conversation_id': conversation['id'],
        'tools': ['web', 'research']
    }
)
result = response.json()
print(result['response'])

JavaScript Integration

// Create conversation
const conversation = await fetch('/api/conversations', {
    method: 'POST',
    headers: {'Content-Type': 'application/json'},
    body: JSON.stringify({title: 'My AI Chat'})
}).then(r => r.json());

// Send message with intelligent caching
const response = await fetch('/api/chat', {
