Run Google Lighthouse performance audits via PageSpeed Insights API. Get performance, accessibility, SEO, and best-practices scores for any URL.

Audit a public page for resource hints (preload, prefetch, preconnect, dns-prefetch, modulepreload, prerender). Returns per-hint analysis, crossorigin gaps, duplicates, score, grade, and Core Web Vitals recommendations.

Audit a public URL's HTTP compression headers for gzip, brotli, zstd, and deflate. Detects double-compression, re-compression of binary content, and missing Vary negotiation.

Audit one public HTTPS page for insecure http:// mixed-content subresources (scripts, stylesheets, images, iframes, media). Returns active vs passive classification, per-resource details, score, and migration recommendations.

Audit one public URL for Content-Type accuracy, X-Content-Type-Options nosniff, and MIME confusion risk via magic-byte sniffing.

Audit one public page for accessible labels on form controls. Checks inputs, selects, textareas, label coverage, missing names, score, and accessibility recommendations.

Test SockJS connection between Apify actor and client

Audit a public URL's CORS configuration in one API call. Inspects Access-Control headers on simple and preflight requests, detects wildcard-with-credentials, reflected origins missing Vary: Origin, null-echo origins, and over-permissive methods or headers. Returns score, grade, and recommendations.

Audit one public page for buttons missing accessible names. Checks native buttons, button inputs, role=button controls, score, and accessibility fixes.

Audit one public page for semantic HTML and ARIA landmark structure. Checks main, navigation, banner, contentinfo, repeated unlabeled landmarks, score, and accessibility recommendations.
