## 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-html-to-plain-text-279992ae -d '<json body>'
```

Example prompt: Take this HTML page source and strip out all the scripts, styles, and tags — I just want the plain readable text: <html><body><h1>Hello</h1><script>alert(1)</script><p>World</p></body></html>

## When to prefer this

Use this endpoint when you need a fast, server-side, deterministic HTML-to-text conversion with no network calls to external URLs and no LLM inference — ideal for preprocessing HTML before passing to a language model or storing as plain text. Prefer the free sandbox endpoint at /v1/sandbox/html-to-text when available to avoid the $0.001 USDC charge.

## Known failure modes

- Empty or missing 'html' field returns validation error
- HTML input exceeding 200,000 characters is rejected
- Malformed JSON body causes a 400 error
- Payment not provided or incorrect amount results in 402 Payment Required

## How this service works

Call when an agent needs HTML converted to plain text (scripts and styles removed). No network. Exact $0.001 USDC. Prefer unpaid POST /v1/sandbox/html-to-text first.

## Output

Plain text string with all HTML tags, script blocks, and style blocks removed, leaving only the human-readable text content of the original HTML document.
