> AgentShelf XPath Script Type Extractor is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-02).

Extracts the `type` attributes of all `<script>` elements from a public URL or raw HTML using the XPath expression `//script/@type`.

## 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-script-type-extractor-b5a17b12 -d '<json body>'
```

Example prompt: Can you pull out all the script type attributes from https://example.com — I want to know what values appear in the `type` field of every script tag on that page.

## When to prefer this

Use this endpoint when you need to specifically extract the `type` attributes of `<script>` tags from a page or HTML fragment via XPath. It is SSRF-safe, making it suitable for processing public URLs in agent pipelines. Prefer the free sandbox POST /v1/sandbox/xpath-script-type endpoint first if available to avoid the $0.002 USDC charge. Choose this over general-purpose HTML parsers when you want a lightweight, targeted extraction of only script type attributes.

## Known failure modes

- URL is unreachable or returns a non-200 status — endpoint may return an error or empty result
- HTML exceeds 200,000 character limit — request rejected
- URL shorter than 8 characters or HTML shorter than 1 character — validation error
- SSRF-blocked internal/private URLs — request rejected for security reasons
- Page has no script elements or no script elements with type attributes — empty result returned

## How this service works

Call when an agent needs type attributes of //script via //script/@type from a public page or HTML (SSRF-safe). Exact $0.002 USDC. Prefer unpaid POST /v1/sandbox/xpath-script-type first.

## Output

A list of `type` attribute values extracted from all `<script>` elements found in the provided URL or HTML, using the XPath selector `//script/@type`. May return an empty list if no script elements have explicit type attributes.
