Which spec versions are supported?

OpenAPI 3.0, 3.1 and Swagger 2.0, in JSON or YAML

Where do the response bodies come from?

From the response example in the spec when there is one; otherwise a realistic body is synthesised from the response schema and its field names

Do path parameters work?

Yes. A templated path such as /users/{id} matches any value in that segment, so a real id resolves to the endpoint example

How long does the mock last?

It answers for 24 hours, then expires
