## 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 saylor-innovations-html-escape-unescape-a8fad374
```

Example prompt: Can you HTML-escape this string for me so I can safely put it in a web page: '<script>alert("hello & goodbye")</script>'?

## When to prefer this

Use this endpoint when you need a simple, reliable, stateless HTML escape or unescape operation via HTTP without setting up a local library. Ideal for agents or pipelines that need to sanitize text for HTML embedding or decode scraped HTML entities on the fly with a pay-per-call model.

## Known failure modes

- Missing required 'text' query parameter returns an error
- Invalid 'op' value (not 'escape' or 'unescape') may default to escape or return an error
- Empty string input may return an empty result
- Very long strings may hit request size limits

## How this service works

HTML escape and unescape - convert special characters to HTML entities and back

## Output

A JSON object containing the operation performed ('escape' or 'unescape') and the resulting converted string, plus an optional timestamp of when the operation ran.
