## 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 x402-agentutility-seo-snapshot-bc664e83 -d '<json body>'
```

Example prompt: Can you run a full SEO snapshot on https://www.notion.so/product — I want the page title, meta description, canonical, OG tags, all internal and external links, and keyword suggestions seeded from 'productivity app'?

## When to prefer this

Choose this endpoint when you need on-page SEO metadata, link analysis, and keyword suggestions from a single URL in one call — replacing three separate API calls with one composite request. Ideal for agents running competitor audits, content gap analysis, or programmatic SEO pipelines at $0.04 per page. Prefer over calling individual metadata, link, and keyword APIs separately when latency and cost efficiency matter.

## Known failure modes

- Unreachable or non-public URL returns an error or degraded:true with partial results
- Bot-blocking pages may return empty metadata or missing links
- Pages with no outbound links yield internal_count and external_count of 0
- Keyword suggestions may be limited if the page title is too generic or short
- Component failures are indicated per-entry in the components array with ok:false

## How this service works

Audits a page's on-page SEO in one call: head metadata, link profile, and keyword ideas. Give it a URL and get back head metadata (title, description, canonical, OG/Twitter cards), the internal/external link breakdown, and ranked keyword suggestions seeded from your seed_keyword or the page's own title. One paid call replaces three: ideal for content-gap analysis, SEO audits, competitor page reviews, programmatic SEO pipelines. Composite: one call runs url-metadata-extract + link-extract in parallel, then keyword-suggest seeded from the page title. Use it as an SEO research API for agents.

## Output

A JSON object containing: the audited URL; head metadata (title, description, canonical, language, OG object, Twitter object); a links object with total count, external count, internal count, and an array of link items with href, anchor text, and is_external flag; a keywords object with count and ranked suggestion strings; a components array showing which sub-services ran (url-metadata-extract, link-extract, keyword-suggest) with per-component latency and success status; a degraded flag; and the seed_keyword_used.
