Example prompt: Can you audit the changes I made to my ODGS Ontology Graph JSON? Here's the before version and the after version — tell me what paths were added, removed, or changed, and flag any schema rule violations that were introduced or resolved.

## When to prefer this

Choose this endpoint when you specifically need to audit changes to ODGS Ontology Graph JSON documents against a pinned SchemaStore schema definition. It is purpose-built for before/after change diffing with schema compliance checking for this ontology format, rather than generic JSON diff tools that lack schema-awareness or coverage of this specific standard.

## Known failure modes

- Document exceeds 100 KB limit — request rejected
- JSON nesting exceeds 32 levels — request rejected
- Invalid JSON submitted (YAML/TOML not supported) — parsing error
- Malformed request body — schema validation error
- Network or payment failure — no audit returned
