Block Integrates Bitcoin Lightning into AI-Powered Payment Protocol

Block has joined the x402 Foundation and added Bitcoin Lightning Network support to the payment standard used by AI agents. The integration is expected to enable automated, small-value payments for digital services without human intervention.

The x402 protocol allows AI agents and web services to independently cover costs for API access, data, and digital service fees. This automation is key to making high-volume, agent-driven commerce feasible.

Block views Lightning's low fees and fast processing speeds as ideal for the small-value, high-frequency payments that AI agents require. The company's decision to fold Lightning into x402 signals its bet on Bitcoin's place in payment infrastructure for AI transactions.
