Your current Crocodoc account will not be affected in any way by this release. It will continue to function as expected, and your pricing plan will not change. You will not be charged for use of the View API during the beta. However, you will continue to be charged for your current Crocodoc account usage.
Any changes to Crocodoc pricing will occur after the View API is out of beta in early 2014, and will be communicated well in advance of billing changes.
