Api Endpoint

a11y-preflight

Static accessibility (WCAG 2.2) check of a UI markup fragment for JSX, TSX, Vue, Angular or HTML. Detects missing image alt, unlabeled form controls, buttons and links with no accessible name, skipped heading levels, invalid ARIA, non-interactive click handlers, duplicate ids, positive tabindex and low static colour contrast. Returns a pass, caution or block verdict with per-finding WCAG criterion, element and line. Accessibility indicators, not a legal compliance guarantee.
