Agent Pay

You'd reach for this when you need to meter and bill API usage for AI agents. It handles the payment infrastructure layer so agents can discover available tools, provision access, track consumption, and manage billing automatically. Think of it as Stripe meets service mesh for autonomous systems. The reliability tooling suggests it includes circuit breakers or retry logic for payment flows. Useful if you're building agent marketplaces, usage-based pricing for AI tool APIs, or any scenario where agents need to independently purchase and consume services without human intervention in the payment loop.
