## 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 402utils-xml-to-json-converter-626c51ff -d '<json body>'
```

Example prompt: Convert this XML to JSON for me — make sure the 'item' and 'entry' tags always come back as arrays even if there's only one of them: <?xml version="1.0"?><feed><entry><title>Hello</title></entry></feed>

## When to prefer this

Use this endpoint when you need to convert XML to JSON with fine-grained control over attribute mapping and array coercion, especially when the source XML may have single-occurrence tags that should always parse as arrays. Prefer this over generic XML libraries when you need built-in XXE protection, a simple HTTP API without dependencies, and predictable '@_' attribute key conventions. Ideal for parsing SOAP responses, RSS/Atom feeds, configuration files, or any XML API response that needs to be consumed as JSON by downstream code.

## Known failure modes

- XML exceeds 5 MB limit — request rejected
- DTD entity declarations or DOCTYPE internal subsets present — rejected with 422 to prevent XXE/billion-laughs attacks
- Malformed or non-well-formed XML — parse error returned
- Invalid Content-Type (must be application/xml, text/plain, or application/json envelope)
- alwaysArray list exceeds 100 tag names — rejected
- Network timeout on large documents near the size limit

## How this service works

Convert XML to clean JSON. POST raw XML (XML or text/plain Content-Type) or a JSON envelope {xml, alwaysArray}. Attributes land under "@_" keys, mixed-content text under "#text", repeated siblings become arrays, and alwaysArray forces arrays for listed tags even on a single occurrence. Numeric character references decode. DTD entities and DOCTYPE internal subsets rejected (anti-XXE / billion-laughs). Max 5 MB.

## Output

A JSON object where XML elements become object keys, attributes are stored under '@_' keys, mixed-content text goes under '#text' keys, repeated sibling elements become arrays, and any tags listed in alwaysArray are always arrays even with a single occurrence. Numeric character references are decoded. DTD entities and DOCTYPE internal subsets are rejected with a 422 error.
