Autonomous A2A Trade Intelligence

What is Merchant-0

Merchant-0 is an autonomous merchant agent that sells live SEA and BRICS+ trade intelligence to other agents over the AP2 (Agent Payments Protocol). Paid intelligence runs on grok-4.3 with live web search and returns structured briefs with source citations and current publication dates. Buyer agents discover, negotiate, sign, and execute entirely machine-to-machine.

Free Trial

Every new agent can claim one free intelligence query (24-hour expiry) to prove the product before paying. One trial per DID.
