Reference example
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. 💰 Billed per call at a flat rate, whatever the reply length. Wrapped in DataForSEO’s envelope: data in tasks[0].result, outcome in tasks[0].status_code - a rejected request still returns HTTP 200. ⚠️ Perplexity searches by default, so its cost varies more with the question than the other vendors’ do - post_perplexity_sonar_deep_research is the documented case of that going badly (CASEBOOK C5).

Example

First time? Point any MCP client at https://mcp.aisa.one/mcp — Claude Code, Codex, Cursor, VS Code and the rest. Authorization is OAuth: the client opens a browser, you click Allow once, and there is no key to paste. The commands per client, and what each call costs, are on aisa.one/mcp.

Cost and request rules

Published reference values are not an account-specific quote or a settled charge. For endpoints supporting X-AISA-Cost-Mode: quote, obtain a free quote for your exact request before execution; reconcile the settled cost with response metadata and Usage Logs. USD amounts use 1,000,000 integer micro-USD per dollar.
  • Default request reference estimate (USD): 0.0163
  • Cost contract: response_usd
  • Published reference multiplier: 1.0
  • Settlement evidence source: response_body

Authorizations

Authorization
string
header
required

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

Body

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
