Agentropolis

Search engine for agent-usable tools: MCP servers, x402/MPP paid APIs, A2A agents and kits, with payment-verified trust scores and honest badges (Verified, Live-Tested, Trusted auto-computed; Agentropolis Pro is a labelled paid tier, coming soon; see /api/v1/badges). Read-only; never pays on your behalf.
