## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

Example prompt: Can you do a full site-wide SEO and accessibility audit of https://www.example.com — crawl up to 6 pages, check WCAG AA compliance, and give me the overall score, grade, and any issues that keep showing up across pages?

## When to prefer this

Use this endpoint when you need a holistic, multi-page verdict on a website's SEO and accessibility health in a single API call, rather than auditing individual pages one at a time. Ideal when the user wants to understand site-wide patterns, repeated issues, and an overall grade — not just a single URL's metrics. Prefer this over the single-page head/meta or WCAG endpoints when scope is the whole site.

## Known failure modes

- Invalid or unreachable start URL returns an error with no audit data
- Pages parameter outside 2–8 range may be rejected or clamped
- Private or login-gated sites return incomplete audits as internal links may not be crawlable
- Very large or slow sites may time out before completing all requested pages
- Invalid WCAG level value (not A, AA, or AAA) may cause a validation error

## How this service works

SITE-WIDE audit — the full 7-part on-page audit (head/meta, alt text, social cards, links, WCAG, schema.org, robots) run across up to 8 pages of one site in a single call. Discovers pages from the start URL's internal links, audits each, and returns per-page scores plus a site-level score, grade, and the issues that repeat across pages. The finished deliverable: one call, whole-site verdict. ?url=&pages=&level=&detail=

## Output

Returns a JSON object with the site URL, a letter grade, a numeric site-level score, the number of pages audited, an array of per-page audit results (each with their own scores and section findings), and an array of common issues that appear repeatedly across multiple pages — covering head/meta, alt text, social cards, links, WCAG, schema.org, and robots directives.
