API – Accessibility Checker

The Accessibility Checker API is a tool designed for developers, integrators, and QA teams who want to automate accessibility testing of websites and web applications according to the WCAG 2.1 standard (levels A and AA). Thanks to flexible integration methods, the API enables fast accessibility analysis in both development and production environments.

The API supports both automated and manual tests, which can be executed in synchronous or asynchronous mode depending on your subscription plan. It’s an ideal solution for teams that want to automate the accessibility auditing process and integrate it directly into their CI/CD pipelines to detect WCAG issues early in the development cycle.

👉 To try the tool manually, you can do it directly here (opens in a new tab).

Best Practices for Integrating the Accessibility Checker API

To make the most of the Accessibility Checker API, consider the following recommendations:

  • Validate automated test results with manual reviews — not all WCAG issues can be detected automatically.
  • Use asynchronous mode for large-scale scans (e.g., entire websites or SPAs) to avoid timeouts and performance limits.
  • Integrate the API into your CI/CD pipeline to detect accessibility issues before production deployment.
  • Monitor reports and track changes — accessibility is an ongoing process, not a one-time audit.

By following these best practices, your application will not only comply with WCAG 2.1 but also provide a more inclusive and user-friendly experience for all users.
