How this service works
WCAG accessibility audit of a public URL using headless Chromium and axe-core: violation/pass/incomplete counts by impact, per-rule detail, and a 0-100 score.
Output
Returns a JSON object with: a 0-100 accessibility score, the audited and final URLs, the WCAG level and viewport used, an audit timestamp, a summary object with total violation/pass/incomplete counts and a breakdown by impact (critical, serious, moderate, minor), an array of violations each with rule ID, description, impact, WCAG tags, help URL, and per-node HTML snippets and failure summaries, plus an array of incomplete (needs-review) rules.
Example use cases
Pre-launch accessibility compliance check
“Before we go live, can you audit https://myapp.com for WCAG 2.2-AA accessibility issues on desktop and give me the score and a breakdown of any critical or serious violations?”
Mobile accessibility review for a client site
“Run a WCAG 2.1-AA accessibility audit on https://client-portfolio.com using a mobile viewport — I need the full list of violations with their impact levels and the HTML selectors where they occur.”
Continuous accessibility regression monitoring
“Check https://staging.myblog.com against WCAG 2.2-AA on desktop and tell me if there are any new accessibility violations compared to a perfect score — especially anything flagged as critical or moderate.”
Technical details
Endpoint
GEThttps://x402-api-24223879872.us-east1.run.app/v1/a11y-audit?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a programmatic, per-rule WCAG accessibility audit with axe-core severity breakdown (critical/serious/moderate/minor) and a normalized 0-100 score for any public URL, especially when you need both desktop and mobile viewport options and support for both WCAG 2.1-AA and 2.2-AA standards. Prefer it over manual audits or browser extensions when automating CI/CD checks or agent-driven compliance workflows.
Side effects
- Private, loopback, or link-local URLs are rejected with an error
- URL that times out or returns non-200 in headless Chromium results in an audit failure
- Malformed or missing 'url' query parameter returns a validation error
- Sites with heavy JavaScript that doesn't render in time may yield incomplete audits
- Paywalled or login-required pages will only audit the publicly visible portion
