## 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-css-script-type-extractor-7651cf4f -d '<json body>'
```

Example prompt: Can you fetch this page at https://example.com and pull out all the script[type] attribute values from its HTML script tags?

## When to prefer this

Choose this endpoint when you need to specifically extract script[type] attribute values from a public URL or raw HTML in a reliable, SSRF-safe environment. It is ideal when you have a URL you cannot fetch yourself or need a sandboxed extraction. Prefer the free unpaid POST /v1/sandbox/css-script-type first if available; use this paid endpoint when that is unavailable or rate-limited.

## Known failure modes

- URL is unreachable or returns a non-200 response
- URL resolves to an internal/private IP (SSRF blocked)
- HTML input exceeds 200,000 character limit
- No script tags with a type attribute found (empty result)
- Malformed HTML prevents parsing
- URL parameter too short (under 8 chars) or too long (over 2048 chars)
- Payment not completed or insufficient USDC balance

## How this service works

Call when an agent needs script type values via script[type] from a public page or HTML (SSRF-safe). Exact $0.008 USDC. Prefer unpaid POST /v1/sandbox/css-script-type first.

## Output

Returns the list of script[type] attribute values found across all <script> elements in the provided page URL or raw HTML, enabling the agent to understand what kinds of scripts are embedded (e.g. text/javascript, module, application/json, text/template, application/ld+json).
