The missing piece in this stack: the agent spending its own money
autonomously. Buying a domain requires a payment method — today that's
a human credit card pre-provisioned somewhere. L402 (HTTP 402 +
Lightning) was designed for exactly this: agent gets an invoice, pays
in milliseconds, gets cryptographic proof. No card on file, no account.
Built l402-kit to make this dead simple to add to any API:
