"Agent Rails" is not a named product in the candidates. The closest matches are payment and commerce rail products for AI agents: Agentry offers identity, trust and Cashu ecash payment endpoints 111, Synmerco offers escrow, verification and settlement rails with agent resolution and search 212, and x402 Agent Pay offers an x402 facilitator on Base L2 3.
