## 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 signaldesk-ai-html-unescape-f685b40e -d '<json body>'
```

Example prompt: Can you unescape the HTML entities in this text for me: '&lt;b&gt;Hello &amp; welcome&lt;/b&gt; &mdash; it&#39;s great to see you!'?

## When to prefer this

Choose this endpoint when you need a fast, low-cost ($0.001 USDC) programmatic HTML entity decoder without setting up a local library — particularly useful in serverless or agent workflows where installing an HTML parser is impractical. Best for strings up to 4096 characters. If you need to parse full HTML documents or extract structured content from HTML, prefer a dedicated HTML parser.

## Known failure modes

- Text exceeds 4096 character limit — request will be rejected
- Malformed or incomplete HTML entities may be passed through unchanged
- Non-HTML-encoded input is returned as-is without error
- Payment failure via x402 protocol blocks request execution

## How this service works

Evidence-backed autonomous AI jobs and paid data tools. Queue/D1/cron run outside the chat; free quotas and bounded execution apply.

## Output

A JSON object with a 'decoded' field containing the fully unescaped plain text string, with all HTML entities (such as &lt;, &gt;, &amp;, &quot;, &#39;, numeric entities, etc.) replaced by their literal character equivalents.
