Frequently asked questions
What spec format does it accept?
It works with OpenAPI (formerly Swagger) specifications, the standard format for describing REST APIs.
Does it support both JSON and YAML specs?
OpenAPI specs are commonly written in JSON or YAML; provide your spec and it's parsed into readable documentation.
Can I use this for an internal API?
Yes. It's well suited to quickly documenting internal or private APIs from their spec without deploying separate documentation tooling.
