## 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`):

```sh
zero fetch --capability webbersites-full-on-page-seo-accessibility-bundle-audit-d1d9a84f
```

Example prompt: Can you run a full SEO and accessibility audit on https://www.example.com — use WCAG AA level — and give me the overall score, grade, and all the itemized deductions?

## When to prefer this

Choose this endpoint when you need a comprehensive, all-in-one on-page audit in a single API call rather than calling seven separate specialized endpoints. It is more cost-effective ($0.05 vs ~$0.09 individually) and ideal when you want a unified score and deduction breakdown across SEO, accessibility, social metadata, structured data, and crawler settings simultaneously. Prefer individual sibling endpoints only if you need a single specific check without the overhead of the full bundle.

## Known failure modes

- URL is unreachable or returns non-200 — audit cannot fetch the page
- URL is a private/intranet address — no public access
- Invalid WCAG level parameter (only A, AA, AAA are valid)
- Page blocks crawlers via robots.txt — partial data returned
- Timeout on slow-loading pages — incomplete sub-reports
- Malformed or missing 'url' query parameter — validation error returned

## How this service works

FULL on-page audit bundle — seven analyses in one call against a single URL: head/meta SEO audit, alt-text check, social-card check with og:image verification, internal-link analysis, WCAG accessibility check (choose level), schema.org structured-data audit, and a robots/llms.txt crawler summary. Returns a transparent 0-100 score with itemized deductions plus every full sub-report. Pieces individually total ~$0.02; the bundle adds the unified score free.

## Output

Returns a JSON object with a 0-100 numeric score, a letter grade, an array of itemized deductions explaining point losses, and a 'sections' object containing the full sub-reports for each of the seven analyses: head/meta SEO, alt-text, social card (og:image), internal links, WCAG accessibility, schema.org structured data, and robots/llms.txt crawler verdicts.
