## 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-title-extractor-e650763f -d '<json body>'
```

Example prompt: Can you fetch the page title from https://example.com/blog/article — just grab whatever is in the <title> tag?

## When to prefer this

Use this endpoint when you need only the HTML title element text from a public webpage or HTML snippet, and you want SSRF-safe fetching with a predictable low cost ($0.006 USDC). Prefer the free sandbox POST /v1/sandbox/xpath-title endpoint first if available. Choose this over general-purpose scraping tools when you need a focused, lightweight title-only extraction without broader DOM parsing overhead.

## Known failure modes

- URL is not publicly accessible or returns a non-200 status — extraction fails
- Page has no <title> element — returns empty or null result
- URL exceeds 2048 characters or HTML exceeds 200,000 characters — request rejected
- SSRF-blocked URL (private IP, internal host) — request rejected for security
- Malformed HTML where title tag cannot be parsed — may return empty result
- Network timeout fetching the URL — request fails

## How this service works

Call when an agent needs text of //title via //title from a public page or HTML (SSRF-safe). Exact $0.006 USDC. Prefer unpaid POST /v1/sandbox/xpath-title first.

## Output

Returns the text content of the <title> element found in the HTML of the given URL or raw HTML input. If a URL is provided, the service fetches the page (SSRF-safe) and extracts the title; if raw HTML is provided, it parses it directly. The result is the plain text string from the title tag.
