## 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 one-engine-html-unescape-575c7db1 -d '<json body>'
```

Example prompt: Can you unescape this HTML-encoded string for me: '&lt;b&gt;ONE&lt;/b&gt; &amp; more'? I need the actual characters back, not the entity codes.

## When to prefer this

Choose this endpoint when you need a cheap, pay-per-call HTML entity decoder with no subscription required, especially in agentic pipelines processing web-scraped or API-returned text at scale. Ideal when your agent already uses x402/Base micropayments and needs a stateless, fast utility call.

## Known failure modes

- Missing or empty 'text' field in request body returns an error or empty result
- Malformed JSON body returns a 400-level error
- Network timeout or Cloudflare Workers cold-start latency on rare occasions
- Payment failure via x402 protocol blocks the call before processing

## How this service works

Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.

## Output

A JSON object with a 'text' field containing the unescaped/decoded version of the input string, with all HTML entities (e.g. &lt;, &gt;, &amp;, &quot;) replaced by their corresponding characters.
