## 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-article-tag-extractor-fc2d120c -d '<json body>'
```

Example prompt: Can you pull out the article:tag meta property from this page — https://www.example-news-site.com/tech/ai-article-2024?

## When to prefer this

Use this endpoint when you need to specifically extract the article:tag meta property from a public webpage or HTML blob, particularly when SSRF safety is a requirement. It is more targeted than a general meta-tag scraper and costs only $0.003 USDC per call. Prefer the free sandbox endpoint POST /v1/sandbox/profile-article-tag for testing before incurring charges.

## Known failure modes

- URL points to a private/internal network address (SSRF blocked, rejected)
- URL is unreachable or returns a non-200 status
- HTML input exceeds 200,000 character limit
- No article:tag meta property present in the page (empty result)
- Malformed HTML prevents parsing
- URL string too short (< 8 chars) or too long (> 2048 chars)
- Both url and html fields omitted

## How this service works

Call when an agent needs article:tag extracted from a public page or HTML (SSRF-safe). Exact $0.003 USDC. Prefer unpaid POST /v1/sandbox/profile-article-tag first.

## Output

Returns the extracted value(s) of the article:tag meta property found in the page HTML — either fetched from the provided URL or parsed directly from supplied HTML. If the tag is absent, likely returns an empty or null result.
