Capabilities

Tools 8

audit_public_site

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, execute JavaScript, fetch assets, or run site-wide link checks. Use page_offset to continue when more sitemap pages remain.

Discovered
audit_public_webpage

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. Use only URLs the user owns or is authorized to inspect.

Discovered
audit_seo_metadata

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.

Discovered
check_broken_links

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.

Discovered
generate_validation_report

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.

Discovered
validate_css

Use this when raw CSS source is supplied. Parses it inside the Worker and returns syntax messages without contacting an external service.

Discovered
validate_html

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.

Discovered
validate_schema_markup

Use this for a focused JSON-LD syntax check of supplied HTML. It parses JSON only and does not validate Schema.org vocabulary semantics.
