Reference example
把 user_prompt 发给某个 Perplexity 模型并同步返回回复。model_name 必须来自 get_dataforseo_ai_perplexity_llm_responses_models——sonar、sonar-pro、sonar-reasoning-pro。web_search_country_iso_code 限定搜索范围,另外三家没有这个参数。返回 model_name、input_tokens、output_tokens、reasoning_tokens、web_search、money_spent、datetime、items 和 fan_out_queries。💰 按次固定计费,与回复长度无关。看响应里的 money_spent 才知道一个 prompt 实际花了多少。 响应包在信封里:数据在 tasks[0].result,成败在 tasks[0].status_code——请求被拒时 HTTP 仍是 200。 ⚠️ Perplexity 默认就会搜索,所以它的成本随问题波动比另外三家大得多——post_perplexity_sonar_deep_research 就是这件事出事的记录在案的案例(CASEBOOK C5)。

示例

第一次用? 把任意 MCP 客户端指向 https://mcp.aisa.one/mcp —— Claude Code、 Codex、Cursor、VS Code 都可以。鉴权走 OAuth:客户端打开浏览器,你点一次 Allow,不需要粘贴任何 key。各客户端的具体命令和每次调用的价格见 aisa.one/zh-cn/mcp。

必填

Bearer authentication header of the form Bearer <token>, where <token> is your auth token.

请求体

application/json
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_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_tokens
integer | null

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

temperature
number | null

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_p
number | null

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_code
string | null

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_message
string | null

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
(object | null)[] | null

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?"}]

tag
string | null

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
