​
Scenario

Chat-based product finder on an e-commerce site or marketplace that remembers user preferences across sessions.

​
Extraction

From on-site chat, searches, clicks, and purchases, GetProfile maintains:
  • style_preferences[]: “minimalist”, “streetwear”, “pastel colors”
  • constraints: budget, size, materials to avoid (e.g. wool)
  • brand_affinities[] and brand_avoidances[]
  • decision_speed: impulse buyer vs researcher
This comes from conversation like “I hate wool sweaters” or “I usually spend under $100”.

​
Injection

For each conversation turn:
  • GetProfile injects a compact preference block:
    • “User likes minimalist, neutral colors, hates wool, typical budget under $80, prefers sustainable brands.”
  • It injects a few recent preference-confirming memories (click/purchase events) to help retrieval.
The LLM then uses this as:
  • Additional filters in its retrieval/system prompt (“avoid wool, budget under 80”),
  • Guidance for how to present results (“3 options, sorted by sustainability and price”).

​
Impact

  • Fewer irrelevant suggestions, higher conversion, and a user who feels understood without filling forms.

​
Implementation

import OpenAI from 'openai';

const client = new OpenAI({
apiKey: process.env.GETPROFILE_API_KEY,
baseURL: 'https://api.yourserver.com/v1',
defaultHeaders: {
'X-GetProfile-Id': userId,
'X-Upstream-Key': process.env.OPENAI_API_KEY,
},
});

// Product recommendation request
const response = await client.chat.completions.create({
model: 'gpt-5',
messages: [
{
role: 'system',
content: 'You are a helpful shopping assistant. Recommend products that match the user\'s style and budget preferences.',
},
{
role: 'user',
content: 'I need a new winter jacket.',
},
],
});
// GetProfile injects style preferences, budget constraints, and past purchases
