Install with your agent
Agent handoff
Hand the extracted package to your coding agent with a concrete install brief instead of figuring it out manually.
- Download the package from Yavira.
- Extract it into a folder your agent can access.
- Paste one of the prompts below and point your agent at the extracted folder.
New install
I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Tell me what you changed and call out any manual steps you could not complete.
Upgrade existing
I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Summarize what changed and any follow-up checks I should run.

lnget - Lightning-Native HTTP Client
lnget is a wget/curl-like CLI that natively handles L402 (Lightning HTTP 402) authentication. When a server responds with HTTP 402 and an L402 challenge, lnget automatically pays the Lightning invoice and retries with the paid token. Source: github.com/lightninglabs/lnget
Quick Start
# 1. Install lnget skills/lnget/scripts/install.sh # 2. Initialize config (auto-detects local lnd) lnget config init # 3. Fetch an L402-protected resource lnget --max-cost 1000 https://api.example.com/paid-data
Installation
skills/lnget/scripts/install.sh This will: Verify Go is installed Run go install github.com/lightninglabs/lnget/cmd/lnget@latest Verify lnget is on $PATH To install manually: go install github.com/lightninglabs/lnget/cmd/lnget@latest Or build from source: git clone https://github.com/lightninglabs/lnget.git cd lnget make install
Downloads

Payment Control
# Set maximum auto-pay amount (satoshis) lnget --max-cost 5000 https://api.example.com/expensive.json # Set maximum routing fee lnget --max-fee 50 https://api.example.com/data.json # Preview without paying (shows 402 challenge details) lnget --no-pay https://api.example.com/data.json # Custom payment timeout lnget --payment-timeout 120s https://api.example.com/data.json
Output Modes
# JSON output (default, best for programmatic use) lnget --json https://api.example.com/data.json # Human-readable output lnget --human https://api.example.com/data.json # Verbose mode (shows L402 flow details) lnget -v https://api.example.com/data.json # Disable progress bar lnget --no-progress -o file.zip https://api.example.com/file.zip
Token Management (lnget tokens)
Tokens are cached per-domain at ~/.lnget/tokens/<domain>/token.json and reused automatically on subsequent requests. # List all cached tokens lnget tokens list # Show token for a specific domain lnget tokens show api.example.com # Remove token for a domain (forces re-authentication) lnget tokens remove api.example.com # Clear all tokens lnget tokens clear --force
Configuration (lnget config)
# Initialize config file at ~/.lnget/config.yaml lnget config init # Show current configuration lnget config show # Show config file path lnget config path
Lightning Backend (lnget ln)
# Check backend connection status lnget ln status # Show detailed node info lnget ln info LNC (Lightning Node Connect) # Pair with a node via LNC pairing phrase lnget ln lnc pair "your-pairing-phrase" # Ephemeral pairing (no session persistence) lnget ln lnc pair "phrase" --ephemeral # List saved LNC sessions lnget ln lnc sessions # Revoke a session lnget ln lnc revoke <session-id> Neutrino (Embedded Wallet) # Initialize embedded neutrino wallet lnget ln neutrino init # Get address to fund wallet lnget ln neutrino fund # Check wallet balance lnget ln neutrino balance # Show sync status lnget ln neutrino status
Configuration File
Config lives at ~/.lnget/config.yaml. Run lnget config init to create it. Note: lnget config init may generate incorrect YAML key names (e.g., tlscertpath and macaroonpath instead of tls_cert and macaroon) due to missing yaml struct tags in the lnget source. Use the example below as the reference config format. If your config was generated by lnget config init, verify the ln.lnd keys match the format shown here. l402: max_cost_sats: 1000 # Max invoice to auto-pay max_fee_sats: 10 # Max routing fee payment_timeout: 60s # Payment timeout auto_pay: true # Enable auto-payment http: timeout: 30s max_redirects: 10 user_agent: "lnget/0.1.0" allow_insecure: false ln: mode: lnd # Options: lnd, lnc, neutrino lnd: host: localhost:10009 tls_cert: ~/.lnd/tls.cert macaroon: ~/.lnd/data/chain/bitcoin/mainnet/admin.macaroon network: mainnet output: format: json progress: true verbose: false tokens: dir: ~/.lnget/tokens Environment variables override config with LNGET_ prefix: export LNGET_L402_MAX_COST_SATS=5000 export LNGET_LN_MODE=lnc export LNGET_LN_LND_HOST=localhost:10009

L402 Flow
When lnget encounters a 402 response: Parses WWW-Authenticate: L402 macaroon="...", invoice="..." header Decodes the macaroon and BOLT11 invoice Checks invoice amount against --max-cost Stores a pending token (crash recovery) Pays the invoice via the configured Lightning backend Stores the paid token with preimage at ~/.lnget/tokens/<domain>/ Retries the request with Authorization: L402 <macaroon>:<preimage> Subsequent requests to the same domain reuse the cached token without payment.
Budget-Aware Fetching
# Check cost before committing result=$(lnget --no-pay --json https://api.example.com/data.json) cost=$(echo "$result" | jq -r '.invoice_amount_sat // 0') if [ "$cost" -le "$BUDGET" ]; then lnget --max-cost "$BUDGET" -q https://api.example.com/data.json fi
Parsing JSON Output
# Extract just the response body lnget --json -q https://api.example.com/data.json | jq '.body' # Check if payment was required lnget --json https://api.example.com/data.json | jq '.l402_paid'
Testing with Insecure Connections
# For local development with aperture (no TLS) lnget -k https://localhost:8081/api/data
