## 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 delx-html-escape-012f6517 -d '<json body>'
```

Example prompt: HTML-escape this string for me so I can safely drop it into an HTML page without XSS risk: '<script>alert("hello")</script> — thanks, Johnson & Associates'

## When to prefer this

Choose this endpoint when your agent pipeline dynamically injects text into HTML and you need a lightweight, stateless, pay-per-call HTML-escaping step without managing a library or server-side dependency. It is ideal for agents that produce HTML emails, web snippets, or templated pages where user-generated or LLM-generated text must be sanitized on the fly. Prefer it over a full sanitization library when you only need character-level HTML entity encoding and not full HTML parsing or stripping.

## Known failure modes

- Empty or missing 'text' field returns an error or empty result
- Extremely large payloads may be rejected or time out
- Payment failure via x402 will block the call from completing
- Non-string input types may cause a validation error

## How this service works

HTML-escape text for safe embedding. Call when you inject agent text into HTML without XSS. Returns escaped text for $0.001 USDC via x402 on Base. No network, no keys, no retention; first-party local JSON only. Results are advisory; the caller owns budgets, auth, and production controls.

## Output

Returns the input text with all HTML special characters converted to their safe entity equivalents (e.g. < becomes &lt;, > becomes &gt;, & becomes &amp;, " becomes &quot;), ready for direct embedding in HTML without XSS risk.
