FAQ
What stays private?
Does it call my API?
No. OpenAPILens only parses the document you paste and makes no network requests.
Does it validate every OpenAPI rule?
No. It inventories operations and highlights missing operation IDs; use a full OpenAPI linter for the complete contract.
Are schemas shown?
No. The report keeps the view focused on endpoints and does not render schema or security values.
