About

Agent Economics is an independent project focused on AI agent economic infrastructure. We believe the future internet economy will be driven by autonomous transactions between AI agents — and x402 + MCP are the foundational protocols enabling this shift.

We've deployed 4 production x402 endpoints on Cloudflare Workers, published an MCP tool server, and submitted to the Open 402 Directory. We also offer AI agent development services on major freelancing platforms.
