FAQ

What OpenAPI versions are supported?

The viewer supports both OpenAPI 3.x and Swagger 2.0 specification formats. It parses the paths, operations, and schema objects from either version.

Does it support YAML input?

Yes. You can toggle between JSON and YAML format. The built-in YAML parser handles common OpenAPI structures including nested objects, arrays, and inline values.

Can I use this with my private API specs?

Absolutely. All parsing and rendering happens entirely in your browser. Your API specification never leaves your device, making it safe for proprietary and internal APIs.

How are endpoints organized?

Endpoints are grouped by their tags as defined in the specification. Each group can be expanded or collapsed, and individual endpoints reveal their full details when clicked.

Does it show request and response schemas?

Yes. For endpoints with a request body, the viewer displays the schema properties including name, type, required status, and description. Response codes with their descriptions are also shown.

What HTTP methods are color-coded?

GET (green), POST (blue), PUT (orange), DELETE (red), PATCH (yellow), and OPTIONS/HEAD (purple) each have distinctive color badges for quick visual identification.
