Read-only. Unreachable sites are not charged.
Output
A structured JSON report (or rendered HTML page) containing: HTTP status code, final URL after redirects, HTTPS validity, page title and meta description, Open Graph and Twitter card fields, robots.txt and sitemap presence, noindex flag, up to 50 links with pass/warn/fail status, og:image load result, desktop (1280×800) and mobile (390×844) JPEG screenshots, edge TTFB, real-browser load time, image alt text coverage, heading outline, mobile overflow flags, and a ranked fix list with priority (P1/P2/P3), check name, problem description, and recommended fix.

Example use cases
Pre-launch landing page audit
“I'm about to launch my startup's landing page at https://myapp.io — can you run a full site audit and tell me what P1 and P2 issues I need to fix before going live?”
SEO and social card check
“Check https://myblog.com/new-post to see if the Open Graph tags, Twitter card, and meta description are all set up correctly, and whether the og:image actually loads.”
Broken link and mobile readiness review
“Can you audit https://myclient.com for broken links and mobile overflow issues, and also grab desktop and mobile screenshots so I can see how it looks?”
Technical details
Endpoint
GEThttps://quickbuild.quynguyenbac.workers.dev/launchcheck/full?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a single comprehensive pre-launch or ongoing quality check for a public webpage — covering SEO, social sharing, broken links, performance, accessibility basics, and visual screenshots in one call. It is especially suited for landing pages, blog posts, or marketing sites where you want a P1-P3 prioritized fix list without running multiple separate tools. Prefer it over individual checkers when you need both technical SEO metadata and visual screenshot evidence in one response.
Side effects
- Private or reserved IP addresses are refused with an error
- Unreachable/down sites return an error but are not charged
- Invalid or malformed URLs return a validation error
- Sites with aggressive bot-blocking may return incomplete results
- Screenshots may fail for sites requiring authentication
