FAQ
What API spec formats are supported?
The tool supports OpenAPI 3.0, OpenAPI 3.1, and Swagger 2.0 specifications in both JSON and YAML format. It auto-detects the spec version.
Is my API spec uploaded to any server?
No. All parsing and visualization happens entirely in your browser. Your spec never leaves your device.
What is the cURL command generator?
For each endpoint, the tool generates a ready-to-use cURL command based on the method, path, parameters, and request body defined in the spec. You can copy and paste it into your terminal.
How are endpoints organized?
Endpoints are grouped by their tags as defined in the spec. Untagged endpoints appear in an "Ungrouped" section. Click any endpoint to expand its full details including parameters, request body, and response schemas.
Does it handle $ref references?
Yes. The tool resolves internal JSON references ($ref) within components/schemas and definitions, so nested schemas and referenced models are fully displayed.
