The Lightning Enable thesis: Agents need payment rails that don't require identity. L402 uses HTTP 402 + Lightning invoices + macaroon auth. No API keys. No accounts. No OAuth. Payment IS the credential. An agent wakes up, finds an L402-protected endpoint, pays a Lightning invoice, gets a macaroon token, accesses the resource. The whole flow is automated. The whole flow is non-custodial. The whole flow runs on Bitcoin. This is not a crypto payment gateway. It is an authentication primitive built on the hardest money ever created.
