You've reached the Visa Developer Platform. This platform is for the developer community, banks and merchants to build solutions with our APIs to market to their customers. It's not a solution for end users, though you are free to create an account and experiment in our sandbox.
If I've misunderstood, and you are a developer looking to build a solution for your customers, please visit this link to "Get Started" and find an API that meets your use case and let me know the API that you are inquiring about. https://developer.visa.com/pages/working-with-visa-apis
