## About

# broker-price: Authenticated Price Research

Searches prices across all bound platforms using the user's own account session — the same search they'd do manually in each app. No web scraping, no anti-bot issues.

## Workflow

1. Receive product info (from broker-recognize or user description)
2. Build platform-specific search queries
3. For each bound platform with valid session:
   - Search active listings → extract prices, conditions
   - Search sold listings → extract actual transaction prices
4. Calculate:
   - Price range (min → max)
   - Median active listing price
   - Median sold price (preferred metric)
   - Market sentiment (seller-favorable / balanced / buyer-favorable)
5. Recommend price: **median of sold comparables** (when available), or 5% below active median (when no sold data)
6. Present transparency report with data sources

## Script

```bash
python3 scripts/research.py --product product.json
    # Searches all bound platforms, outputs transparency report
```

## Fallback

If session-based search fails (expired session, platform API change), fall back to Claude Code's WebSearch for comparable listings. Results from fallback are clearly labeled as lower-confidence estimates.
