Frequently Asked Questions
Is JSON Schema compatible with OpenAPI 3.1?
Yes! OpenAPI 3.1 achieved 100% dialect compatibility with JSON Schema (2020-12), allowing standard JSON schemas to be embedded directly into OpenAPI definitions.
What if my schema has no title property?
If no title is declared, the converter defaults to Model, which you can rename to your entity name.
