PDF Accessibility Checker is currently accessible through the REST API only.

PDF Accessibility Checker

The Accessibility Checker API verifies if PDF files meet the machine-verifiable requirements of PDF/UA and WCAG 2.0. It generates a report summarizing the findings of the accessibility checks. Additional human remediation may be required to ensure the reading order of elements is correct and that alternative text tags properly convey the meaning of images. The report contains links to documentation that assists in manually fixing problems using Adobe Acrobat Pro.
