## 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 pennyrail-html-entities-converter-e36ddd9b -d '<json body>'
```

Example prompt: Can you decode the HTML entities in this string for me: 'Caf&eacute; &amp; Bistro &mdash; great food &lt;3' and give me back the plain readable text?

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-use HTML entity encoding or decoding operation without standing up your own text-processing infrastructure. It is well-suited for AI agent pipelines that occasionally encounter HTML-encoded text in scraped content, API responses, or user-submitted data and need it normalized to plain text. At $0.001 USDC per call it is cost-effective for low-to-moderate volume single-string conversions.

## Known failure modes

- Missing or malformed 'input' object returns a 4xx error
- Payment not included or insufficient USDC causes 402 Payment Required response
- Invalid or non-text input type may return an error or empty result
- Network timeout on the Vercel serverless function under cold start conditions
- Ambiguous conversion direction if the API requires explicit mode selection but none is provided
