Do Your Free API Units Reset Monthly?

I have searched and searched to find this out but haven't found a clear answer. Can anyone confirm if the free API units displayed in our API center are renewed each month or are the free units gone once we use them all? Thanks in advance -- =~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~ Als

What Version Supports 10,000 GEO Targets

My tech team setup our API app using version v201101 I know this version is about to be depreciated but my question is this: Version v201101 seems to have a 300 positive GEO target limit, is that correct? Does v201109 have a 300 positive GEO target limit or is it 10,000 now? Thank in advance
