When I first signed up for Aspose Free Trial, I was met with an old dashboard with an icon of lifebelt/lifesaver. There was a section called Billing History or something where I could see all my calls and how many credits they charged as well.
I logged in again a few days ago and that old dashboard is replaced with a newer, modern-looking one. It’s good, but I can’t find the Billing History anymore that shows how many credits were charged for a call 
???
The thing is that the old Billing History showed that credits were only charged for API calls that uploaded a file to Aspose’s cloud server. All other calls, like reading textboxes and checkboxes from PDF, authenticating using ‘/connect/token’ and ‘/oauth2/token’ were FREE.
Was that old dashboard showing incorrect information? Because your pricing terms are all over the place.
I am using Free Trial of Aspose.PDF API with 150 free credits per month and I have a couple of questions:
- Does authentication API calls charge credits? (’/connect/token’ and ‘/oauth2/token’)
- Does uploading a file to Aspose Cloud Storage charge credits?
- Does reading PDF data through API calls charge credits? (e.g. ‘/pdf/{pdf_name}/fields/textbox’)
- Does deleting a file from Aspose Cloud Storage charge credits?
I’m concerned, because authentication needs to be done every 24 hours, and to use PDF API calls, you need to have the files uploaded to Aspose Cloud Storage. And PDF API calls and Aspose Cloud Storage require calls to two different authentication endpoints (/connect/ and /oauth2/). This means that I need at least 2 API calls per 24 hours for authentication, 2 API calls for files (uploading and deleting), and then however many calls I’ll need for the actual operations.
Authentication: 2 credits
Aspose Storage: 2 credits per file
PDF operations: x credits
That’s 4 credits + x credits per file. This will deplete the free 150 credits pretty fast…
Is this true? If not, then please clarify! Thanks
