Agentic Commerce Toolkit

This plugin provides a complete toolkit for agent-driven Lightning Network commerce. Three skills work together to enable agents to send and receive micropayments over the Lightning Network using the L402 protocol.

Components

Skill	Purpose
lnd	Run Lightning Terminal (litd: lnd + loop + pool + tapd)
lnget	Fetch L402-protected resources (pay for data)
aperture	Host paid API endpoints (sell data)

Full Setup Workflow

Step 1: Install All Components

bash

# Install litd (Lightning Terminal — bundles lnd + loop + pool + tapd)
skills/lnd/scripts/install.sh

# Install lnget (Lightning HTTP client)
skills/lnget/scripts/install.sh

# Install aperture (L402 reverse proxy)
skills/aperture/scripts/install.sh

Step 2: Set Up the Lightning Node

bash

# Start litd container (testnet by default)
skills/lnd/scripts/start-lnd.sh

# Create an encrypted wallet
skills/lnd/scripts/create-wallet.sh --mode standalone

# Verify node is running
skills/lnd/scripts/lncli.sh getinfo

Step 3: Fund the Wallet

bash

# Generate a Bitcoin address
skills/lnd/scripts/lncli.sh newaddress p2tr

# Send BTC to this address from an exchange or another wallet

# Verify balance
skills/lnd/scripts/lncli.sh walletbalance

Step 4: Open a Channel

bash

# Connect to a well-connected node (e.g., ACINQ, Bitfinex)
skills/lnd/scripts/lncli.sh connect <pubkey>@<host>:9735

# Open a channel
skills/lnd/scripts/lncli.sh openchannel --node_key=<pubkey> --local_amt=1000000

# Wait for channel to confirm (6 blocks)
skills/lnd/scripts/lncli.sh listchannels

Step 5: Configure lnget

bash

# Initialize lnget config (auto-detects local lnd)
lnget config init

# Verify connection
lnget ln status

Step 6: Fetch Paid Resources

bash

# Fetch an L402-protected resource
lnget --max-cost 1000 https://api.example.com/paid-data

# Preview without paying
lnget --no-pay https://api.example.com/paid-data

# Check cached tokens
lnget tokens list

Step 7: Host Paid Endpoints (Optional)

bash

# Start your backend service
python3 -m http.server 8080 &

# Configure aperture to protect it
skills/aperture/scripts/setup.sh --insecure --port 8081

# Start the L402 paywall
skills/aperture/scripts/start.sh

# Other agents can now pay to access your endpoints
# lnget --max-cost 100 https://your-host:8081/api/data

Agent-to-Agent Commerce

The full loop for autonomous agent commerce:

text

Agent A (buyer)                    Agent B (seller)
─────────────                      ─────────────
lnd node running                   lnd node running
  ↓                                  ↓
lnget fetches URL ──────────────→ aperture receives request
                                     ↓
                                   Returns 402 + invoice
  ↓
lnget pays invoice ─────────────→ lnd receives payment
  ↓                                  ↓
lnget retries with token ───────→ aperture validates token
                                     ↓
                                   Proxies to backend
  ↓                                  ↓
Agent A receives data ←──────────  Backend returns data

Buyer Agent Setup

bash

# One-time setup
skills/lnd/scripts/install.sh
skills/lnget/scripts/install.sh
skills/lnd/scripts/start-lnd.sh
skills/lnd/scripts/create-wallet.sh --mode standalone
lnget config init

# Fund wallet and open channels (one-time)
skills/lnd/scripts/lncli.sh newaddress p2tr
# ... send BTC ...
skills/lnd/scripts/lncli.sh openchannel --node_key=<pubkey> --local_amt=500000

# Ongoing: fetch paid resources
lnget --max-cost 100 -q https://seller-api.example.com/api/data | jq .

Seller Agent Setup

bash

# One-time setup
skills/lnd/scripts/install.sh
skills/aperture/scripts/install.sh
skills/lnd/scripts/start-lnd.sh
skills/lnd/scripts/create-wallet.sh --mode standalone

# Configure and start paywall
skills/aperture/scripts/setup.sh --port 8081 --insecure

# Start backend with content to sell
mkdir -p /tmp/api-data
echo '{"market_data": "..."}' > /tmp/api-data/data.json
cd /tmp/api-data && python3 -m http.server 8080 &

# Start aperture
skills/aperture/scripts/start.sh

# Buyers can now access:
# https://your-host:8081/api/data.json (100 sats per request)

Cost Management

Agents should always control spending:

bash

# Set a hard limit per request
lnget --max-cost 500 https://api.example.com/data

# Check cost before paying
lnget --no-pay --json https://api.example.com/data | jq '.invoice_amount_sat'

# Track spending via token list
lnget tokens list --json | jq '[.[] | .amount_paid_sat] | add'

Security Summary

Component	Security Model
Wallet passphrase	Stored at ~/.lnget/lnd/wallet-password.txt (0600)
Seed mnemonic	Stored at ~/.lnget/lnd/seed.txt (0600)
L402 tokens	Stored at ~/.lnget/tokens// per domain
lnd macaroons	Standard lnd paths at ~/.lnd/data/chain/...
Aperture DB	SQLite at ~/.aperture/aperture.db

For production use with significant funds, use watch-only mode with a remote signer container. See the lightning-security-module skill for details.
