How this service works
Site audit: Audit one public http or https page: Lighthouse scores, DNS, SPF, DMARC, DKIM selectors, TLS, security headers and subdomains. Verza calls a render worker and does not fetch the page itself. An empty body is a 402 when the worker can run. A private or loopback host is HTTP 400 after payment is verified and is not settled. A busy or unreachable worker is HTTP 503 with Retry-After and is not settled.
Output
Returns a JSON object containing: overall site score (0-100), DNS records (A, MX, NS, AAAA), TLS certificate issuer and expiry details, Lighthouse scores for performance, SEO, accessibility, and best practices along with top issues, detected subdomains, security headers present and missing, email security records (SPF, DMARC, DKIM selectors), timing data, and the final resolved URL.
Example use cases
Pre-launch website health check
“Before we go live, can you audit https://staging.acme.com and tell me if there are any missing security headers, TLS issues, or Lighthouse performance problems I should fix?”
Client SEO and accessibility report
“I need a full audit of https://clientsite.co.za — pull the Lighthouse SEO, accessibility, and performance scores plus any top issues so I can include them in the client report.”
Email security posture check
“Can you check whether https://mybusiness.co.za has SPF, DMARC, and DKIM properly configured, and let me know if anything is missing that could cause our emails to land in spam?”
Technical details
Endpoint
POSThttps://verza.dev/v1/site-audit?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a comprehensive, multi-dimensional audit of a public website covering performance, SEO, accessibility, DNS health, TLS validity, security headers, and email security in a single call. It is particularly useful for agency workflows, pre-launch checks, or compliance reviews where breadth of coverage matters more than depth in any single dimension. It is not the right choice if you only need a narrow check such as pure DNS lookup or standalone Lighthouse CI integration.
Side effects
- Non-public or unreachable URL returns an error or timeout
- Invalid URL format rejected at input validation
- Very slow sites may hit timing limits (total_ms can reach 21,000ms+)
- Sites with aggressive bot-blocking may return incomplete Lighthouse data
- Private/internal URLs (e.g. localhost) will fail as they are not publicly accessible
