THEN Use the Letta API client to create an agent with memory blocks (e.g., 'human' and 'persona') and tools. Then send messages to the agent using `client.site_1.messages.create()`. Requires a Letta API key from app.letta.com and installation of the TypeScript or Python SDK.

import Letta from '@letta-ai/letta-client';
const client = new Letta({ apiKey: 'YOUR_KEY' });
const agent = await client.agents.create({ model: 'openai/gpt-5.2', memory_blocks: [{ label: 'human', value: 'Name: Timber' }], tools: ['web_search'] });
await client.agents.messages.create(agent.id, { input: 'Hello' });
