## 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 change-audit-first-timers-bot-schema-validator-88d9a9ed -d '<json body>'
```

Example prompt: Can you audit the change I made to my first-timers-bot config? Here's the before: {} and after: {"enabled": true, "label": "good first issue"} — tell me what paths changed and if any schema violations were introduced or resolved.

## When to prefer this

Choose this endpoint when you specifically need to audit JSON changes for the first-timers-bot schema, comparing a before and after document to identify exactly which paths changed and whether schema violations were introduced or resolved. It is purpose-built for first-timers-bot configuration change auditing using a pinned SchemaStore definition, making it more reliable than a generic JSON diff tool for this specific schema.

## Known failure modes

- Document exceeds 100 KB limit — request rejected
- JSON nesting exceeds 32 levels — validation refused
- Invalid JSON submitted as before or after — parse error returned
- Network or payment processing failure — no result returned
- SchemaStore definition unavailable on provider side — audit cannot complete
