Example prompt: Can you validate this JSON document against the lego.json schema and tell me if there are any rule violations or invalid fields?

## When to prefer this

Choose this endpoint when you specifically need to validate a JSON document against the lego.json schema as defined in SchemaStore. It is ideal for CI/CD pipelines, developer tooling, or agent workflows that need to verify lego.json correctness without standing up a local validator. Prefer this over generic JSON Schema validators when you want a pre-pinned, stable lego.json schema definition applied automatically.

## Known failure modes

- Document exceeds 100 KB size limit — validation rejected
- JSON nesting exceeds 32 levels — validation rejected
- Input is not valid JSON (YAML/TOML not supported) — parse error returned
- Schema definition unavailable or pinned version mismatch — validation may fail or return unexpected results
- Malformed request body — HTTP error returned
