According to CoinMeta, _exchange_gap posted on its platform that x402 and foundation have incorporated Lightning Network payment standards into their open internet payment protocols. This protocol was initially developed by Coinbase with the aim of allowing AI agents and applications to automatically complete payments and continue executing tasks without the need to create accounts, enter credit card information, or manage API subscriptions, after receiving a "402 payment required" response. The protocol is now governed by Linux Foundation and involves participation from companies such as Cloudflare, Google, AWS, Visa, Mastercard, Stripe, and American Express. With the integration of Lightning Network, AI agents can use聪 to call API, data, computing power, MCP tools, and other digital resources, and prove payments in a cryptographic manner through Lightning Network pre-images.
