How this service works
Deterministic security audit of a website or domain, computed live: HTTP security headers graded A-F with a fix per failed check, TLS certificate and protocol (expiry, chain trust, hostname match, legacy TLS), email anti-spoofing (SPF with recursive DNS-lookup count, DMARC, MTA-STS, TLS-RPT, BIMI, DKIM on common selectors), DNS (A/AAAA/NS/CAA), RDAP registration data, security.txt and robots.txt. The full audit returns a 0-100 score and the top 5 fixes. Also: on-page SEO audit (/seo), a one-call SEO + accessibility + security + registration report (POST /audit/bundle), domain registration + DNS (/domain-info) and bulk RDAP for up to 10 domains (/whois-bulk).
Output
Returns a JSON object with the page URL, an overall 0-100 SEO score, a summary of pass/warn/fail counts, and an array of individual checks — each with an ID (e.g. title, meta_description, sitemap, hreflang), a status (pass/warn/fail), the detected value, and a recommended fix string when applicable.
Example use cases
Pre-launch SEO checklist for new page
“Before we go live, can you audit https://acmecorp.com/new-product-launch for SEO issues — I want to know the score and anything that's failing or needs a fix, especially meta tags, canonical, and structured data.”
Diagnosing a blog post's poor ranking
“My blog post at https://myblog.com/best-coffee-makers isn't ranking and I think there are SEO problems — can you run an audit and tell me what's wrong with the title, meta description, headings, and image alt tags?”
Monitoring client site SEO health
“Run an SEO audit on https://clientsite.com/ and give me a summary of all the pass, warn, and fail checks including the overall score so I can put it in my monthly report.”
Technical details
Endpoint
GEThttps://domainaudit.genexxis.com/seo?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a structured, machine-readable on-page SEO audit of a specific URL with actionable fix recommendations and a numeric score. Prefer it over general web scraping when the goal is specifically SEO diagnostics — it covers a broad set of technical and on-page factors in one call for $0.005. It's ideal for agents building SEO reports, pre-launch checklists, or continuous monitoring workflows.
Side effects
- URL is unreachable or returns non-200 — audit may reflect fetch errors rather than real SEO state
- Malformed or non-https URL input causes validation failure
- Page behind authentication returns limited or no content for analysis
- Dynamic JavaScript-rendered content may not be fully crawled
- robots.txt or sitemap.xml may time out independently, affecting those specific checks
