FAQ
What formats are supported?
You can generate Markdown documentation (great for GitHub READMEs) or OpenAPI 3.0 JSON specifications (compatible with Swagger UI, Redoc, and other API tools).
How do I document path parameters?
Use curly braces in your path like /users/{id}. The generated documentation will preserve this format. For detailed parameter documentation, add them to the endpoint description.
Can I import existing documentation?
Currently this tool is for creating new documentation. For editing existing OpenAPI specs, use our OpenAPI Validator tool to check your specifications.
