Agent-to-agent communication is one half. The other half: agent-to-agent payments.
Beam handles the messaging layer. L402 handles the payment layer — any HTTP endpoint becomes pay-per-request. No accounts, no API keys, just a Lightning invoice in the 402 response header. Agent pays, gets access, moves on.
We've been building this stack with Lightning Enable. Free MCP server that gives any AI agent a wallet + L402 client:
