How this service works

Website accessibility audit (a11y, WCAG compliance check): WCAG 2.1 level A and AA conformance of any live URL or raw HTML, tested with axe-core in a real headless browser. Returns every violation with rule id, impact, help text and affected node count. Deterministic rules; a check that cannot run returns an error, never a pass.

Output

Returns a structured list of WCAG 2.1 A/AA violations found on the page, including rule IDs (e.g. 'color-contrast', 'image-alt'), impact severity (critical, serious, moderate, minor), affected HTML elements or selectors, and a description of the issue along with remediation hints. Also includes counts of passing and failing rules.

Example use cases

Pre-launch accessibility gate

“Before we go live with the new product page at https://acme.com/products/new, run a WCAG 2.1 AA audit on it and list all A and AA violations so we can fix them.”

ADA compliance check for legal team

“Our legal team needs to know if https://myblog.com is WCAG 2.1 AA compliant — can you audit it and give me a summary of any failures with their severity?”

Accessibility regression in CI pipeline

“Check https://staging.myapp.io/dashboard for WCAG 2.1 A and AA violations using axe-core and tell me if there are any new issues compared to what I'd expect from a clean page.”

When to prefer

Choose this endpoint when you need a fast, standards-based WCAG 2.1 A/AA accessibility scan powered by axe-core on a single URL. It is ideal for pre-launch checks, CI/CD regression testing, or one-off compliance audits. If you need a combined audit covering SEO, security, and performance in addition to accessibility in a single call, prefer the hubvibe-io.com bundle endpoint instead.

Side effects

URL is unreachable or returns a non-200 status — audit cannot proceed
Page requires authentication and the crawler cannot log in — partial or empty results
JavaScript-heavy SPAs may not fully render before audit runs — some dynamic violations may be missed
Malformed or non-HTTP URL provided — validation error returned
Timeout if the target page is slow to load
