## 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-profile-meta-description-extractor-559c7886 -d '<json body>'
```

Example prompt: Can you extract the meta description from https://example.com for me? I want to see what SEO description that page is showing to search engines.

## When to prefer this

Use this endpoint when you need to reliably extract the meta description from a public web page or an HTML string without running your own browser or HTML parser. Prefer the free sandbox endpoint (/v1/sandbox/profile-meta-description via POST) first for testing; use this paid endpoint when the sandbox is unavailable or for production use. It is SSRF-safe, making it appropriate for multi-tenant agent environments where arbitrary URL fetching could pose security risks.

## Known failure modes

- URL is not publicly accessible or returns a non-200 HTTP status
- SSRF protection blocks access to internal/private IP ranges or localhost
- No meta description tag found in the HTML
- HTML input exceeds 200,000 character limit
- URL exceeds 2048 character limit or is malformed
- Rate limiting or payment failure (x402 protocol)

## How this service works

Call when an agent needs the meta description extracted from a public page or HTML (SSRF-safe). Exact $0.004 USDC. Prefer unpaid POST /v1/sandbox/profile-meta-description first.

## Output

Returns the extracted meta description string from the provided URL or HTML input. Likely returns the content of the <meta name='description'> tag, or an equivalent (e.g. Open Graph description), along with possible status or error information if no tag is found.
