Example prompt: Can you validate this buf.lock JSON document for me and tell me if it has any schema violations or JSON pointer errors?

## When to prefer this

Choose this endpoint when you need to validate a buf.lock file specifically against the pinned SchemaStore definition, want precise JSON pointer-level error reporting, and your document is under 100 KB. It is not suitable for YAML or TOML variants of buf.lock, documents over 100 KB, or non-buf.lock schemas.

## Known failure modes

- Document exceeds 100 KB size limit — validation refused
- JSON nesting exceeds 32 levels — validation refused
- Input is not valid JSON (YAML or TOML not supported) — parse error returned
- Schema definition unavailable or pinned version mismatch — may produce unexpected results
- Malformed request body — error response with no validation output
