Tools

• audit_public_site ~302 tokens
  Use this for a bounded, sitemap-first audit of a public website the user owns or is authorized to inspect. It fetches at most 8 same-origin HTML pages per call, respects robots.txt, and returns compact page summaries plus deduplicated findings. It does not recursively follow HTML links, authenticate
• audit_public_webpage ~273 tokens
  Use this when the user provides one live public webpage URL. Fetches one bounded static HTML response, then runs HTML validation, SEO/accessibility-signal, and JSON-LD syntax checks. It checks links only when requested and does not crawl, execute JavaScript, authenticate, or fetch linked stylesheets
• audit_seo_metadata ~128 tokens
  Use this for a focused SEO/accessibility-signal check of supplied HTML. It does not fetch a live webpage; use audit_public_webpage for a URL.
• check_broken_links ~203 tokens
  Use this for a focused check of up to 20 public HTTP(S) links found in supplied HTML. It does not fetch base_url, follow redirects, or retain response bodies.
• generate_validation_report ~305 tokens
  Use this when HTML markup is already supplied. Combines Nu HTML validation with local CSS, SEO, accessibility-signal, and JSON-LD syntax checks. It does not fetch a webpage from base_url; use audit_public_webpage for a live URL.
• validate_css ~116 tokens
  Use this when raw CSS source is supplied. Parses it inside the Worker and returns syntax messages without contacting an external service.
• validate_html ~138 tokens
  Use this when raw HTML markup is supplied. Sends that markup to the Nu HTML Checker hosted at validator.nu and returns validation messages. For a live URL, use audit_public_webpage.
• validate_schema_markup ~128 tokens
  Use this for a focused JSON-LD syntax check of supplied HTML. It parses JSON only and does not validate Schema.org vocabulary semantics.
