## 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

Example prompt: Can you convert this YAML to JSON for me: 'name: Alice\nage: 30\nroles:\n  - admin\n  - editor'?

## When to prefer this

Use this endpoint when you need a safe, deterministic conversion of YAML text to JSON without any risk of code execution side effects. Ideal for processing configuration files, CI/CD pipelines, or user-supplied YAML in untrusted contexts where safe parsing is a requirement.

## Known failure modes

- Invalid or malformed YAML returns a parse error
- Input exceeding 100KB may be rejected
- YAML with unsafe schema constructs (e.g. custom tags or executable nodes) will be rejected due to safe-schema restriction
- Empty or missing 'yaml' field returns a validation error

## How this service works

Parse YAML into JSON (safe schema - no code execution).

## Output

A JSON representation of the parsed YAML input, with keys and values mapped to equivalent JSON types. No code is executed during parsing (safe schema only).

## Request schema (JSON Schema)

```json
{
 "type": "object",
 "properties": {
  "yaml": {
   "type": "string",
   "description": "YAML text (max 100KB)"
  }
 }
}
```

## Response schema (JSON Schema)

```json
{
 "type": "json",
 "example": {
  "json": {
   "name": "Ada",
   "tags": [
    "eng"
   ]
  }
 }
}
```
