@Mike Adrian It is recommended to use the computer vision Read API if your PDF document is below 2000 pages under the standard pricing tier. If you have large documents, then you could split the PDF and process accordingly.
You could try using the quickstart available here for any of the languages or use the REST API The call to the API is asynchronous, so the response will be a location URL where the results will be available after the document is processed. You need to use a GET call on the response URL to retrieve the results of the read operation. I hope this helps!!
