Open the PDF document you want to check for accessibility.
Click the Tools tab at the top of the Acrobat window.

You can right-click in the Navigation Pane to show the Accessibility tags panel for more detailed tag inspection.
This runs in the Acrobat app - there is no separate API for this task.
PDF/UA is a specific standard for PDF documents, focusing on how the PDF itself is built to be accessible. WCAG (Web Content Accessibility Guidelines) is a broader set of guidelines for all kinds of digital content, not just PDFs. Many rules for accessible PDFs come from WCAG. Regulated work often needs to meet both standards. Think of PDF/UA as the specific rules for a PDF, and WCAG as the general rules for all digital things.
It is much easier and saves a lot of time to fix accessibility issues in the source document, such as a Microsoft Word file. When you create a PDF from an accessible source document, many accessibility features like headings, lists, and alt text are carried over automatically. Remediating an existing PDF that was not created accessibly can be very time-consuming and complex, often requiring manual adjustments to tags and reading order.
Yes, Acrobat's 'Automatically tag PDF' feature, powered by Sensei, can work with scanned PDFs. It can identify and tag elements like headings, tables, lists, and paragraphs even in image-based documents. However, after auto-tagging, you will still need to manually check the reading order and add alt text for any images, as automation might not get everything perfect in a scanned document.
Reading order is the sequence in which a screen reader or other assistive technology reads the content on a page. It is important because if the reading order is wrong, content might be read out of sequence, making no sense to the user. For example, a caption might be read before its image, or columns of text might be read across instead of down. Correct reading order ensures a logical flow of information.
