Missing API for retrieving outputs

Hi, I saw there is API to retrieve the input items:
https://platform.openai.com/docs/api-reference/responses/input-items

If i’m not mistaken, this only gives the input from the user?
How do I get the complete list of conversation history including output by the response? Am I missing anything?

There is a separate call you have to make to get the AI output associated with a response ID, which is also in a format that differs from the convolution of ‘get input’ and a normal response:

get https://api.openai.com/v1/responses/{response_id}

If you use “conversations” as a server-side chat mechanism instead of reuse of a chain of response IDs, then you can retrieve those entire ‘conversation’ contents as one call.
