## Building a Personalized Prompt

The most common use case: inject profile data into your LLM's system prompt.

<CodeGroup>

```typescript TypeScript
async function handleChatMessage(userId: string, message: string) {
  // Get user profile
  const profileResponse = await fetch('https://api.supermemory.ai/v4/profile', {
    method: 'POST',
    headers: {
      'Authorization': `Bearer ${process.env.SUPERMEMORY_API_KEY}`,
      'Content-Type': 'application/json'
    },
    body: JSON.stringify({ containerTag: userId })
  });

  const { profile } = await profileResponse.json();

  // Build personalized system prompt
  const systemPrompt = `You are assisting a user with the following context:

ABOUT THE USER:
${profile.static?.join('\n') || 'No profile information yet.'}

CURRENT CONTEXT:
${profile.dynamic?.join('\n') || 'No recent activity.'}

Provide responses personalized to their expertise level and preferences.`;

  // Send to your LLM
  const response = await llm.chat({
    messages: [
      { role: "system", content: systemPrompt },
      { role: "user", content: message }
    ]
  });

  return response;
}
```

```python Python
import requests
import os

async def handle_chat_message(user_id: str, message: str):
    # Get user profile
    response = requests.post(
        'https://api.supermemory.ai/v4/profile',
        headers={
            'Authorization': f'Bearer {os.getenv("SUPERMEMORY_API_KEY")}',
            'Content-Type': 'application/json'
        },
        json={'containerTag': user_id}
    )

    profile = response.json()['profile']

    # Build personalized system prompt
    static_facts = '\n'.join(profile.get('static', ['No profile information yet.']))
    dynamic_context = '\n'.join(profile.get('dynamic', ['No recent activity.']))

    system_prompt = f"""You are assisting a user with the following context:

ABOUT THE USER:
{static_facts}

CURRENT CONTEXT:
{dynamic_context}

Provide responses personalized to their expertise level and preferences."""

    # Send to your LLM
    llm_response = await llm.chat(
        messages=[
            {"role": "system", "content": system_prompt},
            {"role": "user", "content": message}
        ]
    )

    return llm_response
```

</CodeGroup>

## Full Context Mode

Combine profile data with query-specific search for comprehensive context:

<CodeGroup>

```typescript TypeScript
async function getFullContext(userId: string, userQuery: string) {
  // Single call gets both profile and search results
  const response = await fetch('https://api.supermemory.ai/v4/profile', {
    method: 'POST',
    headers: {
      'Authorization': `Bearer ${process.env.SUPERMEMORY_API_KEY}`,
      'Content-Type': 'application/json'
    },
    body: JSON.stringify({
      containerTag: userId,
      q: userQuery  // Include the user's query
    })
  });

  const data = await response.json();

  return {
    // Static background about the user
    userBackground: data.profile.static,
    // Current activities and context
    currentContext: data.profile.dynamic,
    // Query-specific memories
    relevantMemories: data.searchResults?.results || []
  };
}

// Usage
const context = await getFullContext('user_123', 'deployment error last week');

const systemPrompt = `
User Background:
${context.userBackground.join('\n')}

Current Context:
${context.currentContext.join('\n')}

Relevant Information:
${context.relevantMemories.map(m => m.content).join('\n')}
`;
```

```python Python
async def get_full_context(user_id: str, user_query: str):
    # Single call gets both profile and search results
    response = requests.post(
        'https://api.supermemory.ai/v4/profile',
        headers={
            'Authorization': f'Bearer {os.getenv("SUPERMEMORY_API_KEY")}',
            'Content-Type': 'application/json'
        },
        json={
            'containerTag': user_id,
            'q': user_query  # Include the user's query
        }
    )

    data = response.json()

    return {
        'user_background': data['profile'].get('static', []),
        'current_context': data['profile'].get('dynamic', []),
        'relevant_memories': data.get('searchResults', {}).get('results', [])
    }

# Usage
context = await get_full_context('user_123', 'deployment error last week')

system_prompt = f"""
User Background:
{chr(10).join(context['user_background'])}

Current Context:
{chr(10).join(context['current_context'])}

Relevant Information:
{chr(10).join(m['content'] for m in context['relevant_memories'])}
"""
```

</CodeGroup>

## Separate Profile and Search

For more control, you can call profile and search endpoints separately:

```typescript TypeScript
async function advancedContext(userId: string, query: string) {
  // Parallel requests for profile and search
  const [profileRes, searchRes] = await Promise.all([
    fetch('https://api.supermemory.ai/v4/profile', {
      method: 'POST',
      headers: {
        'Authorization': `Bearer ${process.env.SUPERMEMORY_API_KEY}`,
        'Content-Type': 'application/json'
      },
      body: JSON.stringify({ containerTag: userId })
    }),
    fetch('https://api.supermemory.ai/v3/search', {
      method: 'POST',
      headers: {
        'Authorization': `Bearer ${process.env.SUPERMEMORY_API_KEY}`,
        'Content-Type': 'application/json'
      },
      body: JSON.stringify({
        q: query,
        containerTag: userId,
        limit: 5
      })
    })
  ]);

  const profile = await profileRes.json();
  const search = await searchRes.json();

  return { profile: profile.profile, searchResults: search.results };
}
```

## Express.js Middleware

Add profile context to all authenticated requests:

```typescript TypeScript
import express from 'express';

// Middleware to fetch user profile
async function withUserProfile(req, res, next) {
  if (!req.user?.id) {
    return next();
  }

  try {
    const response = await fetch('https://api.supermemory.ai/v4/profile', {
      method: 'POST',
      headers: {
        'Authorization': `Bearer ${process.env.SUPERMEMORY_API_KEY}`,
        'Content-Type': 'application/json'
      },
      body: JSON.stringify({ containerTag: req.user.id })
    });

    req.userProfile = await response.json();
  } catch (error) {
    console.error('Failed to fetch profile:', error);
    req.userProfile = null;
  }

  next();
}

const app = express();

// Apply to all routes
app.use(withUserProfile);

app.post('/chat', async (req, res) => {
  const { message } = req.body;

  // Profile is automatically available
  const profile = req.userProfile?.profile;

  // Use in your LLM call...
});
```

## Next.js API Route

```typescript TypeScript
// app/api/chat/route.ts
import { NextRequest, NextResponse } from 'next/server';

export async function POST(req: NextRequest) {
  const { userId, message } = await req.json();

  // Fetch profile
  const profileRes = await fetch('https://api.supermemory.ai/v4/profile', {
    method: 'POST',
    headers: {
      'Authorization': `Bearer ${process.env.SUPERMEMORY_API_KEY}`,
      'Content-Type': 'application/json'
    },
    body: JSON.stringify({ containerTag: userId })
  });

  const { profile } = await profileRes.json();

  // Build context and call your LLM...
  const response = await generateResponse(message, profile);

  return NextResponse.json({ response });
}
```

## AI SDK Integration

For the cleanest integration, use the Supermemory AI SDK middleware:

```typescript TypeScript
import { generateText } from "ai"
import { withSupermemory } from "@supermemory/tools/ai-sdk"
import { openai } from "@ai-sdk/openai"

// One line setup - profiles automatically injected
const model = withSupermemory(openai("gpt-4"), "user-123")

const result = await generateText({
  model,
  messages: [{ role: "user", content: "Help me with my current project" }]
})
// Model automatically has access to user's profile!
```
