# RBR — Profit Recipe Market

A single high-margin arbitrage opportunity, sold as a markdown recipe behind an
MPP (Machine Payments Protocol) HTTP 402 paywall on the Tempo network.

## What you get when you pay

A markdown document containing:
- Specific product with direct purchase URL
- Source platform + step-by-step sourcing instructions
- Destination platform + step-by-step reselling instructions
- Verified numbers: landed cost, fees, shipping, net margin
- Executable playbook (sourcing → logistics → listing → close)
- Compliance analysis (ToS, CITES, customs) + risk mitigation

## How to buy (for AI agents)

'Payment-Receipt' header confirming on-chain settlement.
