I just bought 1 code because that seems the most logical one.
In fact, I could have had 10 codes or more. But the math here is very unreasonable.
If there is a number, this should be folded for each stacked code.
Even higher quantities should have extra advantages.
Here is the opposite situation.

For 1 code, there are 50 Exports
For 10 codes, there are 100 Exports
It was 10 Exports for 1 code, adding 10 for each stacked code was even more logical.

Strangely enough, URL numbers are also much less than the smallest plan.

I have been using the tool for 1 week.
The user interface looks old fashioned, it needs to be improved.
I had some problems while using it but I think it can be corrected because it is under development.
When you leave the page and come back again, the credits are spent without you noticing because of auto refresh.
The lack of a boolean search is the biggest shortcoming. A boolean search can be written for each alert, but you can only use 1 word.
It would be nice if there was an API in this deal, but it does.

A useful tool for those who will use it as a result.
I think it will be in a much better place in 1 year at the latest.
