Agent-Native Protocol · WebMCP Challenge Submission

The First Marketplace Where Negotiation Is a Native Web Capability

Humans set goals. Agents execute the deal. AgentMarket isn't an AI that buys things — it's a marketplace where both sides expose standardized WebMCP tools (make_offer, counter_offer, accept_offer, propose_pickup) directly on the listing page — no scraping, no guessing, no hidden APIs.

Not “an AI marketplace.” There are thousands of those. This is a marketplace designed as an agent-native protocol — where the negotiation capability lives in the webpage itself, discoverable and executable by any WebMCP-compatible agent.
