Do some pdf services require more units than others?
Hi, I've been enjoying the PDF extract API, but I've noticed that it's charging me more units than I've been calling the API. For instance, just now I made 3 extract api calls, but it cost 7 units. Why? Also, I'm currently doing the trial version that comes with 1000 free units. I certainly don't want it charging me more than what I'm using it for when it begins to actually cost me money....
Thanks!
Matt
