CDN Cache and Compression Delivery Contract Gate

Audit public URLs for HTTP caching, validators, compression, Vary behavior, HTTPS delivery, and actionable performance gaps in a structured dataset.

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 how a URL is served: HTTPS, HTTP/2, HTTP/3 (Alt-Svc), Brotli vs gzip compression, cache headers, ETag, HSTS. Returns A-F grade + perf punch-list. Use for web performance audits, CDN verification, hosting QA. Input: url or urls[]. Output: JSON report.

Audit Cache-Control, validators, Brotli/gzip, Vary and stale directives to reduce latency and CDN bandwidth costs.

Checks whether a URL serves compressed responses (br/gzip/deflate) and validates related headers such as Vary: Accept-Encoding for cache correctness. Outputs per-URL results plus SUMMARY and REPORT.

Compare server-rendered JSON-LD on a URL list against a stored baseline and return one pass/fail deploy gate: did this deploy remove rich-result eligibility the last deploy had.

HTTP Status Code Checker — Bulk URL & Redirect Audit

accountable_eel/http-status-lookup

Check any URL's live HTTP status code, final URL after redirects, content type, content size, and server header in one call. No third-party API — the actor makes the request directly. Charged for every URL that returns a real response.

Learn when a deploy, a CDN rule or a proxy change removes or weakens a security header on your production URLs. The Actor compares HSTS, CSP (each directive), X-Frame-Options, X-Content-Type-Options, Referrer-Policy, Permissions-Policy and the cross-origi

Sends a real OPTIONS preflight and a real cross-origin GET from each origin that you name, against each API path that you name. Reports which origins the API accepts, which accept credentials, and every violation class: wildcard with credentials, origin r
