Lnget
Download files with automatic Lightning micropayment handling via L402
What You Can Do
Use lnget to fetch files and data from HTTP endpoints that require L402 Lightning micropayments. The tool automatically detects payment requirements (HTTP 402 responses), processes Lightning payments through your connected LND node, and retries requests—all without manual intervention. You can preview costs before paying, manage authentication tokens, and output results in machine-readable JSON or raw format.
Features
detects HTTP 402 challenges and pays Lightning invoices automatically
preview payment amounts and costs before executing transactions
JSON metadata, raw body content, or piped responses for scripting
list, inspect, and clear cached authentication tokens per domain
supports both LND (macaroon auth) and LNC (pairing phrase) connections
set maximum payment limits to prevent unexpected charges
use via command line or as Claude's Machine Control Protocol tool
check Lightning node status and review command schemas
Example Output
$ lnget --json --print-body https://api.example.com/data.json
{
"status": 200,
"headers": {"content-type": "application/json"},
"body": {"data": "fetched content"},
"payment": {"amount_sat": 250, "status": "paid"}
}
$ lnget tokens list --json
[{"domain": "api.example.com", "amount_sat": 500}, {"domain": "data.provider.io", "amount_sat": 1000}]
$ lnget --dry-run https://paid-endpoint.example.com
{"estimated_cost_sat": 150, "preview": true}
