Since the vulnerability database began charging for API access with only 50 free per day, the value of the extension has really been limited. It would be nice if a feature could be added so that we could enter the number of API requests we get per day (50 for free or some other for those who pay), and have the extension stop after exhausting each of those API calls and then queue up the remaining ones to begin on the following day when the credit is refreshed. This would allow the system to ‘rotate’ through sites each day as API credits were available and provide at least some level of scanning instead of nothing.
Another options would be to be able to include this as part of the maintenance extension so users could just set maintenance tasks for each site they wish to scan and have them run on different days when the API credit is refreshed.
