Live Perplexity LLM Responses
Sends a user_prompt to a Perplexity model and returns its reply, synchronously. model_name must come from get_dataforseo_ai_perplexity_llm_responses_models - sonar, sonar-pro and sonar-reasoning-pro. web_search_country_iso_code scopes the search, which the other three vendors do not offer. Returns model_name, input_tokens, output_tokens, reasoning_tokens, web_search, money_spent, datetime, items and fan_out_queries. Read money_spent on the response to see what a prompt actually cost. Wrapped in DataForSEO's envelope: data in tasks[0].result, outcome in tasks[0].status_code - a rejected request still returns HTTP 200.

请求体
user_promptstring必填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_namestring必填name of the AI model required field model_nameconsists of the actual model name and version name; if the basic model name is specified, its latest version will be set by default; you can receive the list of available LLM models by making a separate request to the following endpoint: https://api.dataforseo.com/v3/ai_optimization/perplexity/llm_responses/models
max_output_tokensinteger可选maximum number of tokens in the AI response optional field minimum value: 1 maximum value: 4096; default value: 2048; Note: if the reasoning model is specified in the request, the output token count may exceed the specified max_output_tokens limit
temperaturenumber可选randomness of the AI response optional field higher values make output more diverse lower values make output more focused minimum value: 0 maximum value: 1.9 default value: 0.77
top_pnumber可选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_country_iso_codestring可选country code for web search localization optional field specify the country ISO code to get localized web search results Note: available only for Perplexity Sonar models example: US
system_messagestring可选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_chainobject[]可选conversation history optional field array of message objects representing previous conversation turns; each object must contain: role string with either user or ai role; message string with message content (max 500 characters); you can specify maximum of 10 message objects in the array; Note: for Perplexity models, messages must strictly alternate between user and AI roles (user → ai); 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?"}]
rolestring必填允许值: user · ai
messagestring必填tagstring可选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
