Description
Use lnget to fetch resources from L402-protected URLs that require Lightning payments.

Use when an HTTP request returns 402 Payment Required and a Lightning micropayment is needed, or when downloading files behind a Lightning paywall.

lnget Skill

Use lnget to fetch resources that require L402 Lightning payments.

When to Use

Use lnget when:

  • Fetching resources from L402-protected APIs
  • Downloading files behind Lightning paywalls
  • Making requests that may require micropayments

Quick Reference

Basic Fetch

# Fetch and print to stdout
lnget https://api.example.com/data

# Save to file
lnget -o output.json https://api.example.com/data

# Quiet mode
lnget -q https://api.example.com/data | jq .

Payment Control

# Set max payment (default: 1000 sats)
lnget --max-cost 500 https://api.example.com/data

# Set max routing fee (default: 10 sats)
lnget --max-fee 5 https://api.example.com/data

# Don't auto-pay (just show 402 response)
lnget --no-pay https://api.example.com/data

Output Formats

# JSON output (default)
lnget https://api.example.com/data

# Human-readable output
lnget --human https://api.example.com/data

Token Management

# List cached tokens
lnget tokens list

# Remove expired/unused token
lnget tokens remove example.com

# Clear all tokens
lnget tokens clear --force

Backend Status

# Check connection status
lnget ln status

# Get node info
lnget ln info

Common Patterns

Fetch JSON API Data

# Fetch and parse JSON
data=$(lnget -q https://api.example.com/data)
echo "$data" | jq '.result'

Download File with Progress

lnget -o file.zip https://api.example.com/file.zip

Resume Partial Download

lnget -c -o large.zip https://api.example.com/large.zip

Check if Token Exists

if lnget tokens show example.com >/dev/null 2>&1; then
  echo "Token cached"
fi

Configuration

Config file: ~/.lnget/config.yaml

Key settings:

  • l402.max_cost_sats: Maximum automatic payment (default: 1000)
  • l402.max_fee_sats: Maximum routing fee (default: 10)
  • ln.mode: Backend type (lnd, lnc, neutrino)
  • output.format: Default output format (json, human)

Exit Codes

  • 0: Success
  • 1: General error
  • 2: Payment exceeded max cost
  • 3: Payment failed
  • 4: Network error

Notes

  • Tokens are cached per-domain automatically
  • JSON output is default (for agent consumption)
  • Use --human for human-readable output
  • Configure lnd connection in ~/.lnget/config.yaml
