Questions
Which spec versions work?
OpenAPI 3.0 and 3.1, and Swagger 2.0. References to other files are not loaded; references inside the same file are followed.
Does it send the request?
No. It only writes the request as text. Copy it and run it where you choose.
Where do the example values come from?
The JSON body starts from an example built from its schema, and what you type is checked against that schema. Nothing you enter is stored.
