Live Gemini LLM Responses

‌‌
Live Gemini LLM Responses endpoint allows you to retrieve structured responses from a specific Gemini AI model, based on the input parameters.

POST

The cost of the task can be calculated on the Pricing page.

All POST data should be sent in the JSON format (UTF-8 encoding). The task setting is done using the POST method. When setting a task, you should send all task parameters in the task array of the generic POST array. You can send up to 2000 API calls per minute, each Live Gemini LLM Responses call can contain only one task.

The number of concurrent Live tasks is currently limited to 30 per account for each platform in the LLM Responses.

Execution time for tasks set with the Live Gemini LLM Responses endpoint is currently up to 120 seconds.

Below you will find a detailed description of the fields you can use for setting a task.

Description of the fields for setting a task:

Field name	Type	Description
`user_prompt`	string	prompt for the AI model required field the question or task you want to send to the AI model; you can specify up to 500 characters in the `user_prompt` field
`model_name`	string	name of the AI model required field `model_name`consists of the actual model name and version name; if the basic model name is specified, its latest version will be set by default; for example, if `gemini-1.5-pro` is specified, the `gemini-1.5-pro-002` will be set as `model_name` automatically; you can receive the list of available LLM models by making a separate request to the `https://api.dataforseo.com/v3/ai_optimization/gemini/llm_responses/models`
`max_output_tokens`	integer	maximum number of tokens in the AI response optional field minimum value: `1` maximum value: `4096`; default value: `2048`; Note: if `web_search` is set to `true` or the reasoning model is specified in the request, the output token count may exceed the specified `max_output_tokens` limit Note #2: if `use_reasoning` is set to `true`, the minimum value for `max_output_tokens` is `1024`
`temperature`	float	randomness of the AI response optional field higher values make output more diverse lower values make output more focused minimum value: `0` maximum value: `2` default value: `1.3`
`top_p`	float	diversity of the AI response optional field controls diversity of the response by limiting token selection minimum value: `0` maximum value: `1` default value: `0.9`
`web_search`	boolean	enable web search for current information optional field when enabled, the AI model can access and cite current web information; Note: refer to the Models endpoint for a list of models that support `web_search`; default value: `false`; The cost of the parameter can be calculated on the Pricing page
`system_message`	string	instructions for the AI behavior optional field defines the AI's role, tone, or specific behavior you can specify up to 500 characters in the `system_message` field
`message_chain`	array	conversation history optional field array of message objects representing previous conversation turns; each object must contain `role` and `message` parameters: `role` string with either `user` or `ai` role; `message` string with message content (max 500 characters); you can specify the maximum of 10 message objects in the array; example: `"message_chain": [{"role":"user","message":"Hello, what’s up?"},{"role":"ai","message":"Hello! I’m doing well, thank you. How can I assist you today?"}]`
`use_reasoning`	boolean	enable reasoning for the AI model optional field when enabled, the model will perform reasoning before generating a response refer to the Models endpoint for a list of models that support `reasoning` default value: `false` Note: if set to `true`, the minimum value for `max_output_tokens` is `1024` Note #2: for Gemini Pro models, the `use_reasoning` will automatically be set to `true`
`tag`	string	user-defined task identifier optional field the character limit is 255 you can use this parameter to identify the task and match it with the result you will find the specified `tag` value in the `data` object of the response

‌
‌‌As a response of the API server, you will receive JSON-encoded data containing a tasks array with the information specific to the set tasks.
‌

`id`	string	task identifier unique task identifier in our system in the UUID format
`status_code`	integer	status code of the task generated by DataForSEO; can be within the following range: 10000-60000 you can find the full list of the response codes here
`status_message`	string	informational message of the task you can find the full list of general informational messages here
`time`	string	execution time, seconds
`cost`	float	cost of the task, USD includes the base task price plus the `money_spent` value

`datetime`	string	date and time when the result was received in the UTC format: “yyyy-mm-dd hh-mm-ss +00:00” example: `2019-11-15 12:57:46 +00:00`
`items`	array	array of response items contains structured AI response data
‘reasoning’ element in the response
`type`	string	type of the element = ‘reasoning’ Note: this element is supported only in reasoning models and is not guaranteed to be returned

Maybe it’s an acorn cup, although it has an open top. The joke could suggest inverting it, but that still leaves it open. I’m not sure how it all ties back to drinking from it!"

The correct response points to a thimble instead, which has an open bottom. The punchline is clear: You can't drink; it's a thimble. The riddle plays on the expectation of a witty response.
