Documentation
What does this tool do?
An intelligent schema inference engine that analyzes sample JSON objects and generates standardized JSON Schema specifications. Automatically detects string formats (email, uuid, uri, date-time), embeds sample values as schema examples, and supports strict validation constraints (`additionalProperties: false`).
When should you use it?
Use this tool to document REST API request/response payloads, generate validation schemas for AJV or backend validation frameworks, or create OpenAPI request body specifications.
