Which version of JSON Schema does this tool generate?

It generates Draft 2020-12 by default — the current recommended dialect — with a Draft-07 legacy option for older OpenAPI, Ajv, and gateway pipelines.

How does it infer string formats like UUID and email?

The engine runs validation regex checks on string values to recognize standard formats including UUIDs, email addresses, URIs, and ISO-8601 timestamps.

Are all properties marked as required by default?

By default, all discovered object properties are added to the required array. You can toggle this off to generate optional properties.

Can I use this generated schema with validation libraries like Ajv?

Yes. The generated Draft 2020-12 schema (or Draft-07 legacy output) works with Ajv, Zod JSON schema parsers, Fastify, and JSON Schema validators in Python, Go, and Java.
