## Sample excerpt

# Buyer Agent

**AI that shops, negotiates in writing, and reports — never buys.**

Give it a want-spec (item, budget, radius, floor/ceiling). It maintains a candidates table, drafts seller inquiries, negotiates by email within your limits, and emails a daily ranked report. When you pick a winner, it produces a closing packet (terms + in-person checklist). It will not send money, place deposits, or e-sign.

## When to use

- Vehicle (or other) shopping with multiple dealers/sellers
- You want written OTD quotes and a paper trail
- You need daily digests instead of chaos in your inbox

## Hard rules

- Identifies as assistant for a **named buyer**
- **Never** purchases, deposits, wires, or e-signs
- Default **approve-before-send** for outbound mail
- No bulk scraping of major listing marketplaces (paste URLs)

## Price

**$24.99 USDC** on Base via x402 unlock.
