Extensions can have different scope depending on which level in your OpenAPI definition you add them:

• Global level: The extension applies to the whole API: all paths, operations, and responses.
• Path level: The extension applies to a specific path, including all operations and responses defined in it.
• Operation level: The extension is applied to a specific operation and its responses.
• Response level: The extension is applied to all responses defined for an operation.
• Status level: The extension is applied to a specific HTTP status code or the default response.
