L402
A machine-native paid authentication protocol based on the Bitcoin Lightning Network. It implements permissionless API micropayments through the HTTP 402 status code and Lightning invoices, and issues a Macaroon credential after payment for authorizing resource access.
Timeline (last 90 days)
L402 is the oldest of the four protocols (originating in 2020), with the smallest GitHub metrics: 91 stars, 8 contributors, zero commits in 90 days, and there is a fork problem—another repository with more stars (l402-protocol/l402, 227 stars) claims to be the new continuation of the same specification.
The four protocols x402, AP2, ACP and L402 currently all handle only single-transaction authorization, and do not define ongoing spending budgets, payee rules or human approval steps.
Argentic是一个基于L402协议和比特币闪电网络的项目，为AI爬虫代理建立付费访问的收费站
L402协议最初由Lightning Labs提出，早期名称为LSAT（Lightning Service Authentication Token），是一种将认证与支付结合的协议
L402协议的机制是：服务器返回402状态码并附带闪电网络发票和macaroon，客户端支付后获得preimage，将macaroon与支付凭证组合作为访问令牌
