# Input Tokens ## Get input token counts `beta.responses.input_tokens.count(**kwargs) -> InputTokenCountResponse` **post** `/responses/input_tokens?beta=true` Returns input token counts of the request. Returns an object with `object` set to `response.input_tokens` and an `input_tokens` count. ### Parameters - `conversation: String | BetaResponseConversationParam` The conversation that this response belongs to.
