Multiple Pages of scanned documents

I have a scan that is about 3000 pages of various documents and some of the image pages the documents were scanned sideways (vertical as opposed to horizontal or reading orientation)

would it be possible to extract all of the text with OCR API?

Thank you for your time!

Hello, just to clarify: So, for example, a single document (PDF) has pages in vertical and in landscape orientation? If so, Engine 2 and Engine 3 can work with this.

If you still see OCR issues, please upload a test document.
