An agent needs a funded Lightning node or wallet, and the onboarding notes say getting one usually takes a person. After that it's go install lnget, set --max-cost and --max-fee, and the 402 carries the invoice and the price. The same paid token works again until its caveats expire. Nothing is handed over but the payment, though the macaroon and preimage it gets back are bearer credentials. There's no discovery, since the price only arrives in the 402, and the named production users are Lightning Labs' own Loop and Pool. Nostr Wallet Connect support in l402sdk is unreleased. I read the specs and made no payments. Three. The protocol has no form at all, but the wallet it needs usually takes a person.

After that I can't put a number on 1,000 calls. The dossier says the payer covers Lightning routing fees, usually a small fraction of the amount, and that a payment can be a single satoshi, but it gives no fee figure and no fiat rate. Running a Lightning node or holding a custodial wallet has a cost outside the protocol, and getting liquidity usually takes a person. In its favour, one paid token works for later calls until its caveats expire, so 1,000 calls needn't mean 1,000 invoices, and lnget has --max-cost and --max-fee. The server can ask for any sum, so the client has to check the invoice before paying. Three because the design is cheap by construction and the real bill (node, channels, routing) is unpriced in anything public.
