## 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-a-title-extractor-e209c3c2 -d '<json body>'
```

Example prompt: Can you extract all the title attributes from the anchor tags on https://example.com/articles and give me a list of them?

## When to prefer this

Use this endpoint when you specifically need to extract title attributes from anchor tags (//a/@title) via XPath from a public URL or raw HTML, and you want SSRF-safe fetching built in. Prefer this over generic scraping tools when you only need anchor title metadata rather than full page content. If a free sandbox endpoint (POST /v1/sandbox/xpath-a-title) is available, try that first to avoid the $0.009 USDC charge.

## Known failure modes

- URL is unreachable or returns a non-200 response — extraction fails with an error
- SSRF protection blocks private/internal IP ranges or localhost URLs — request rejected
- HTML input exceeds 200,000 character limit — request rejected
- No anchor elements with title attributes found — returns empty list
- Malformed HTML may cause incomplete or unexpected XPath results
- URL input exceeds 2,048 character limit — request rejected

## How this service works

Call when an agent needs title attributes of //a via //a/@title from a public page or HTML (SSRF-safe). Exact $0.009 USDC. Prefer unpaid POST /v1/sandbox/xpath-a-title first.

## Output

Returns a list of title attribute values found on all anchor elements (//a/@title) within the specified URL or HTML input. The response contains the extracted string values in order of appearance in the document.
