❓ FAQ

Is Swagger 2.0 supported?

OpenAPI 3.x is the primary target. Swagger 2.0 paths and methods will mostly work, but $ref resolution and complex schemas are only partially supported.

How is the request body filled in?

The tool uses the requestBody example or each property example / default first; otherwise it generates a sample by type (string becomes "string", integer becomes 0, etc.).

Can I run the generated commands as-is?

They contain sample values and placeholder tokens, so replace required parameters and credentials with real values before running them in production.
