VDP is an open platform, so there's really no cost to you to develop your application using any of the APIs in the sandbox. When you're ready to Go Live and promote your project app to production, there are fees for each of the APIs that are used. Fees are evaluated by application because there are many elements that we look at, including the nature of your application and your relationship with any existing Visa partner. Production applications are treated on a case-by-case basis and we are willing to work with you to determine appropriate pricing.
