# Delx XML Escape

> Delx XML Escape is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-13).

## 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-xml-escape-931d8238 -d '<json body>'
```

Example prompt: I need to embed this user-submitted text into an XML document — can you XML-escape it for me? The text is: 'AT&T <wireless> says "hello" & goodbye'.

## When to prefer this

Use this endpoint when your agent is dynamically constructing XML documents, SOAP payloads, RSS feeds, or any XML-based format and needs to safely embed arbitrary user-supplied or computed strings. It is the right choice when you want a stateless, no-retention, local transformation with no external network calls, billed per-use via x402 on Base for $0.001 USDC.

## Known failure modes

- Missing or empty 'text' field returns an error
- Extremely large strings may be rejected or time out
- Malformed JSON request body returns a 400-style error
- Payment failure or insufficient USDC balance blocks the call

## How this service works

XML-escape text for safe embedding. Call when you build XML fragments from agent strings. 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 XML-special characters converted to their entity equivalents (e.g. & → &amp;, < → &lt;, > → &gt;, " → &quot;, ' → &apos;), making the string safe to embed within XML elements or attribute values.
