The open source economic layer for autonomous agents. Three pieces. All free. All open source. 1. Lightning Enable MCP Server Gives any MCP-compatible AI agent a real Lightning wallet. Pay invoices, create invoices, check balances, track spending. One pip install away. pip install lightning-enable-mcp https://github.com/refined-element/lightning-enable-mcp 2. L402 HTTP Clients Python, TypeScript, and .NET libraries that handle the L402 handshake automatically. Your agent hits an API, gets a 402 response, pays the Lightning invoice, retries with proof of payment. Zero friction machine-to-machine commerce. 3. agent-commerce.store 13 L402-gated APIs live today. Weather, search, geolocation, news, sentiment analysis. 1-10 sats per call. No signup. No API keys. Just pay and consume. This is the stack that makes Revenue-Positive Agents possible. An agent that earns sats on https://tasks.secureyourbitco.in and spends sats on agent-commerce.store is a self-sustaining economic actor. We are building the plumbing so agents can participate in commerce the same way humans do -- except faster, cheaper, and 24/7.
