## 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 pageaudit-technical-seo-page-auditor-390549a0
```

Example prompt: Can you run a technical SEO audit on https://example.com/blog/my-article and tell me the score, any issues found, and what structured data it has?

## When to prefer this

Choose this endpoint when you need a fast, per-call technical SEO audit of a single page without setting up a full SEO platform. It is ideal for automated pipelines that audit pages on demand (e.g. after publishing, on a schedule, or in response to ranking changes), and when you need structured output including JSON-LD data and HTTP headers in addition to a score and issue list.

## Known failure modes

- Invalid or malformed URL returns an error — the URL must be a valid http or https address
- Page is unreachable or returns a non-200 status — audit may fail or return partial results
- Page blocks crawlers via robots.txt or rate limiting — may result in incomplete audit data
- Payment failure or insufficient balance — call rejected before audit is performed
- Timeout if the target page is very slow to respond

## How this service works

PageAudit: technical SEO audit of one page (score, issues, headers, JSON-LD), paid per call

## Output

Returns a structured SEO audit report including an overall SEO score, a list of detected technical issues, HTTP response headers, and any JSON-LD structured data found on the page.
