summary: ADA / WCAG Lawsuit Shield & DOM Auto-Patcher
description: 'Returns a FAIL / REVIEW / PASS verdict for a page''s HTML (pasted or fetched from a URL) against the WCAG failures most cited in ADA demand letters: alt text, form labels, unnamed buttons and links, lang, headings, landmarks, skip links, zoom. Each issue carries a CSS selector, source line and fix, with a top-five list, a SARIF 2.1.0 log, a litigation risk score, per-element patched HTML and an interim hotfix. Static HTML only: color contrast, keyboard behaviour and JavaScript-rendered content are not checked, and the output is not legal advice or a conformance claim. If the model patch step fails you still get the full deterministic audit, marked partial.
Price: 0.75 USDC on Base (x402).'
