## 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-dd-extractor-10749358 -d '<json body>'
```

Example prompt: Can you extract all the dd (definition description) elements from this page for me? Here's the URL: https://example.com/product-specs

## When to prefer this

Use this endpoint when you need specifically the <dd> (definition description) elements from HTML — for example, extracting values from definition lists (<dl>/<dt>/<dd> structures) on product pages, profiles, or structured data pages. Prefer the free sandbox endpoint (/v1/sandbox/profile-dd) for testing. Choose this over heading extractors (h1-h6) when you need definition list values rather than headings, and over full-page scrapers when you only need dd element content.

## Known failure modes

- URL points to private/internal IP address — rejected due to SSRF protection
- URL is unreachable or returns non-200 status — fetch failure error
- HTML input exceeds 200,000 character limit — input too large error
- No dd elements found in the page or HTML — empty result returned
- Malformed URL or HTML that cannot be parsed — parsing error

## How this service works

Call when an agent needs dd text extracted from a public page or HTML (SSRF-safe). Exact $0.001 USDC. Prefer unpaid POST /v1/sandbox/profile-dd first.

## Output

Returns the extracted text content of all <dd> (definition description) HTML elements found in the provided URL or HTML, as a structured list or array of strings. SSRF protection ensures only public addresses are fetched.
