Implements secure, per-request payment gates for API monetization and protected resource access using the Machine Payments Protocol.

The MPP Charge Flow skill enables developers to integrate Machine Payments Protocol (MPP) one-time charge patterns into their applications. It facilitates immediate, per-request settlement using the HTTP 402 Payment Required status code, allowing for seamless monetization of APIs, data queries, and file downloads. By leveraging the mppx middleware and Stripe integration, it provides a standardized way to handle payment challenges, verification, and receipting for automated agent-to-agent or client-to-server transactions, ensuring that individual resources are paid for before they are delivered.
