## 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 quant-agent-shop-seo-audit-e7459ab6 -d '<json body>'
```

Example prompt: Can you run a full SEO audit on https://example.com/landing-page and tell me what issues you find — things like title and description lengths, canonical tag, robots meta, Open Graph, JSON-LD, headings, image alt text, and security header grade?

## When to prefer this

Choose this endpoint when you need a fast, comprehensive on-page SEO snapshot of a single URL without requiring JavaScript execution — especially useful for pre-publish or post-publish technical checks. It uniquely covers AI bot crawlability (GPTBot and ClaudeBot) alongside Googlebot, making it ideal for AI-era SEO audits. Prefer it over full-site crawlers when you need a targeted, per-URL result in 1–3 seconds. Not suitable for JavaScript-heavy SPAs, social media URLs, or pages larger than 300 KB.

## Known failure modes

- URL is unreachable or returns a non-200 status — audit fails with an error indicating the HTTP status
- URL points to a social network — requests to social network domains are explicitly refused
- Page exceeds 300 KB — only the first 300 KB of content is read, potentially missing elements below the cutoff
- URL uses JavaScript rendering — dynamic content will not be captured since rendering is not supported
- Invalid or malformed URL format — validation error returned before any request is made
- Target server is too slow — request may time out before a full response is received
- Failed calls are not charged — billing only applies to successful responses

## How this service works

On-page SEO audit of one URL: redirects, title and description lengths, canonical, robots meta and robots.txt for Googlebot, GPTBot and ClaudeBot, hreflang, headings, image alt, links, Open Graph, JSON-LD, sitemap, security headers with a grade, and a list of issues. Use to check a page before or after publishing. Reads the first 300 KB; no JavaScript rendering. Social networks are refused. Typical response 1 to 3 s. Failed calls are not charged.

## Output

Returns a structured report covering: HTTP status and redirect hops, title and meta description character lengths, canonical URL, robots meta directives, robots.txt rules for Googlebot, GPTBot, and ClaudeBot, hreflang tags, heading hierarchy (H1–H6), images missing alt attributes, internal and external link counts, Open Graph tag values, JSON-LD snippets found on the page, sitemap presence, security header assessment with a letter grade, and an aggregated list of detected SEO issues.
