x402 Integrates Lightning Network into Payment Specifications

The x402 Foundation has incorporated Lightning Network payment specifications into its open internet payment standards, according to Bitcoin News. Originally developed by Coinbase and now governed by the Linux Foundation with support from companies including Cloudflare, Google, AWS, Visa, Mastercard, Stripe, and American Express, x402 enables AI agents to automatically handle payments upon receiving a '402 Payment Required' response. With the integration of the Lightning Network, AI agents can now pay for API calls, data, computing power, and MCP tools using Bitcoin, while providing cryptographic proof of payment via Lightning Network pre-images.
