## 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-xpath-dt-text-extractor-ea3bf04a -d '<json body>'
```

Example prompt: Fetch the page at https://example.com/glossary and extract all the definition term (dt) text from it — I need every //dt element's text content from that page.

## When to prefer this

Use this endpoint when you need to extract text specifically from HTML definition term (dt) elements via XPath from a public URL or raw HTML. Prefer the free /v1/sandbox/xpath-dt endpoint first for testing; use this paid endpoint ($0.008 USDC) for production workloads. Choose this over general-purpose scrapers when you specifically need //dt XPath targeting with SSRF safety guarantees.

## Known failure modes

- URL is unreachable or returns non-200 status — extraction fails with an error
- No //dt elements found in the page — returns empty result
- HTML string exceeds 200,000 character limit — request rejected
- URL string shorter than 8 or longer than 2048 characters — validation error
- SSRF-blocked URL (private IP ranges, internal hosts) — rejected for security
- Malformed HTML may result in incomplete or unexpected extraction

## How this service works

Call when an agent needs text of //dt via //dt from a public page or HTML (SSRF-safe). Exact $0.008 USDC. Prefer unpaid POST /v1/sandbox/xpath-dt first.

## Output

Returns the text content of all //dt (definition term) elements found in the page fetched from the provided URL or in the supplied HTML, delivered as structured text output. The extraction is SSRF-safe when fetching remote URLs.
