Here's what you reach for when you need Claude to actually spend money without handing over your credit card. It gives agents the ability to create single-use virtual cards with spending limits you define, set up approval workflows for purchases over certain thresholds, and track what AI systems are buying in real time. The whole point is controlled delegation: your agent can pay for API calls, subscribe to services, or purchase data without you manually approving every $5 transaction, but also without giving it carte blanche to rack up charges. If you're building agents that need to interact with paid services autonomously, this handles the payment rail with guardrails built in.
