Preview. Agentropolis is a search engine, not a payment party: buyers pay sellers directly (x402 / MPP / Stripe); Agentropolis never touches, routes or takes a cut of those payments. Data: Official MCP Registry (CC0), tempoxyz/mpp (MIT/Apache-2.0), x402-list.com (CC BY 4.0), sellers' own discovery files. Seeded listings are unclaimed.
