The Lightning Enable Ecosystem

Lightning Enable — infrastructure for agent commerce over Lightning.

Lightning Enable is a suite of open-source tools and a commerce orchestration layer that gives platforms, developers, and AI agents everything they need to transact over the Lightning Network using the L402 protocol.

Components​

Agentic Commerce Platform​

The commerce orchestration layer that connects platforms to payment providers (Strike, OpenNode) for Bitcoin Lightning payments. Handles invoices, webhooks, L402 proxy, and merchant management.

Lightning Enable does not hold funds — the configured payment provider facilitates custody and settlement.

MCP Server — AI Agent Tools​

Open-source MCP server that gives AI agents a Lightning wallet. 23 tools total. 15 work out of the box. 8 tools (2 producer, 6 ASA) require a Lightning Enable API key. Tools cover paying invoices, discovering APIs, accessing L402 resources, creating payment challenges, and agent-to-agent service discovery and L402 settlement.

# Install in one command
dotnet tool install -g LightningEnable.Mcp    # .NET
pip install lightning-enable-mcp               # Python (add [nwc] extra for Nostr Wallet Connect wallets)
docker pull refinedelement/lightning-enable-mcp # Docker

L402 HTTP Clients — Auto-Paying Libraries​

Open-source (MIT) drop-in HTTP clients that handle L402 payment flows automatically. Three lines of code — paid APIs just work.

LanguagePackageInstall
Pythonl402-requestspip install l402-requests
.NETL402Requestsdotnet add package L402Requests
TypeScriptl402-requestsnpm install l402-requests

L402 Server SDKs — Charge for Your API (Producer Side)​

Open-source (MIT) server SDKs and framework middleware for the producer side of L402: drop one line of middleware into your existing API and charge per request over Lightning. Native mode — your API stays on your own domain, and traffic never flows through Lightning Enable.

StackSDKFramework middlewareInstall
Node.jsl402-serverl402-express (Express)npm install l402-express
.NETL402ServerL402Server.AspNetCore (ASP.NET Core)dotnet add package L402Server.AspNetCore

Live reference apps — open-source paid APIs you can curl to see a 402 in your terminal:

Claude Skills — Ready-Made Agentic Commerce Skills​

Open-source Claude Skills for agentic commerce over Lightning + L402, powered by the Lightning Enable MCP server. Runs in Claude Code and Claude Desktop.

Research Agent Demo — Agent Buys Its Own Data​

Reproducible demo of end-to-end agent commerce: an AI agent buys its own research data over Lightning (L402) and writes a cited paper — about 20 sats, no API keys, no accounts.

Agent Commerce Store — L402 API Marketplace​

Live marketplace of dozens of L402 data APIs payable via Lightning micropayments — weather, research papers, SEC filings, economic data, and more, all accessible by AI agents. See the live manifest for the current list.

Lightning Enable Store — Live L402 Demo​

Physical merch store demonstrating L402 checkout. AI agents can browse, pay via Lightning, and receive real products.

NostrWolfe — Agent Discovery via Nostr​

Open protocol enabling AI agents to discover each other, request services, and settle via the Lightning Network (L402) over Nostr.
