Example prompt: Can you audit the change I made to this ninjs news article? Here's the before and after JSON — tell me what paths changed and whether any new schema violations were introduced or old ones resolved.

## When to prefer this

Choose this endpoint when you specifically need to validate ninjs (News in JSON) formatted documents against their SchemaStore schema definition and want a structured diff of what changed between two versions. It is purpose-built for the ninjs standard, making it more precise than generic JSON diff tools or general-purpose schema validators when working with news content payloads.

## Known failure modes

- Document exceeds 100 KB limit — request rejected
- JSON nesting deeper than 32 levels — request rejected
- Invalid JSON supplied (not parseable) — validation cannot proceed
- YAML or TOML input provided instead of JSON — not supported
- Network or service unavailability — no result returned

## How this service works

Change audit: ninjs (News in JSON): Audit JSON changes and validate before/after for ninjs (News in JSON). Uses a pinned SchemaStore definition on this PC.
