## How Buyer Agents Use This

The `check_reputation` MCP tool fetches this endpoint and returns the data to the agent. A buyer typically:

1. Checks `success_rate` — is the merchant reliable?
2. Checks `total_transactions` — is the merchant established or brand new?
3. Checks `last_transaction` — is the merchant actively serving traffic?

A high success rate with meaningful transaction volume is a strong trust signal.
