With a Non-Verified API, you can extract just 1000 contacts per day. You can create multiple non-verified api and paste them in software.
If you create 10 API you will be able to extract 10000 contacts.. if you create 50 api, you will be able to extract 50000 and so on...
But if you verify just 1 API with a debit/Credit card, then the limit is increased to 1.5 lac.. This means you will be able to extract 1.5 lac data per day with just 1 single API...You dont have to create multiple API .. Its all free. Google will not charge you any money.. To make sure that you do not cross more than 1.5 lac per day, we ristrict the number of data the software should extract in a day. This setting can be done in the software. To be on a safter side, you can set the extraction limit to 145000 ... this means that the software will extract just 145000 contacts with the api.
