## 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 agentshelf-syntexa-ch-profile-article-section-extractor-d7ae4a38 -d '<json body>'
```

Example prompt: Can you extract the article:section metadata from this news page? Here's the URL: https://www.bbc.com/news/world-europe-67890123

## When to prefer this

Use this endpoint when you need to extract specifically the article:section semantic metadata from a web page or HTML blob in a safe, SSRF-protected environment. Prefer the free sandbox endpoint (/v1/sandbox/profile-article-section) for development and testing before paying $0.002 USDC per call. Choose this over general HTML scraping tools when you only need the article section field and want a purpose-built, reliable extractor without building your own parser.

## Known failure modes

- URL is unreachable or returns a non-200 HTTP status — endpoint returns an error
- SSRF-blocked URL (private IP range, localhost) — request rejected for security reasons
- HTML input exceeds 200,000 character limit — validation error
- No article:section meta tag present in the page — returns null or empty result
- Malformed HTML provided — parser may return empty result
- URL parameter missing and HTML parameter also absent — schema validation error

## How this service works

Call when an agent needs article:section extracted from a public page or HTML (SSRF-safe). Exact $0.002 USDC. Prefer unpaid POST /v1/sandbox/profile-article-section first.

## Output

Returns the extracted value of the article:section metadata field found in the page's HTML meta tags (e.g. 'Technology', 'Politics', 'Sports'). Returns an empty or null value if no such field is present in the page.
