## How to call it through Zero

```sh
zero fetch --capability sitesignal-website-dossier-analyzer-d4b0162e
```

Example prompt: Analyze the website at https://stripe.com and give me a compact JSON dossier with an agent-ready Markdown summary — scan up to 2 pages.

## When to prefer this

Choose this endpoint when you need a quick, structured, agent-consumable summary of any public website — especially useful for competitive research, pre-meeting prep, or automated pipeline steps that need website context in JSON or Markdown. Prefer it over raw scraping tools when you want pre-formatted, analysis-ready output rather than raw HTML.

## Known failure modes

- URL is not publicly accessible or behind authentication — returns error
- Private or localhost URLs rejected by URI validation
- maxPages out of range (must be 1–3) — schema validation error
- Website returns non-HTML content (e.g. raw file download) — may produce incomplete dossier
- Rate limiting or timeout if the target site is slow to respond
- Cloudflare Tunnel downtime may cause 502/503 errors

## How this service works

Analyze the public website in the url query parameter into compact JSON and agent-ready Markdown.

## Output

Returns a compact JSON object and agent-ready Markdown document summarizing the analyzed website, including inferred purpose, key content, structure highlights, and other publicly observable metadata extracted from up to 3 pages.
