Visa has launched Visa CLI, a new payment tool from its Visa Crypto Labs division, aimed at facilitating AI agent transactions. Currently in closed beta, the tool allows AI agents to autonomously pay for external API calls without pre-configured accounts, positioning Visa's infrastructure as a native layer for 'command line commerce.' Initial use cases include image and music generation APIs and proprietary data feeds. The launch coincides with other major payment networks exploring agentic commerce. Stripe's Tempo blockchain introduced the Machine Payments Protocol for agent-to-service micropayments, while Mastercard and Google developed Verifiable Intent for secure AI agent transactions. Circle also launched Nanopayments for USDC transactions on testnet. These developments highlight differing approaches to AI agent payments, with Visa CLI bridging traditional finance and crypto solutions.
