Reference example
Sends a user_prompt to a Claude model and returns its reply, synchronously. model_name must come from get_dataforseo_ai_claude_llm_responses_models - names look like claude-sonnet-5, and a plausible-looking guess is rejected. 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.

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): 0.0567
  • 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;
for example, if claude-opus-4-0 is specified, the claude-opus-4-20250514 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/claude/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 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 1025

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
default value: 0.7

Note: temperature cannot be used together with top_p in the same request

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: null

Note: top_p cannot be used together with temperature in the same request

web_search
boolean | null

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

force_web_search
boolean | null

force AI agent to use web search
optional field
to enable this parameter, web_search must also be enabled;
when enabled, the AI model is forced to access and cite current web information;
default value: false;
Note: even if the parameter is set to true, there is no guarantee web sources will be cited in the response

web_search_country_iso_code
string | null

ISO country code of the location used for searching the web
optional field
possible values: 'AR','AT','AU','BE','BR','CA','CH','CL','CN','DE','DK','ES','FI','FR','GB','HK','ID','IN','IT','JP','KR','MX','MY','NL','NO','NZ','PH','PL','PT','RU','SA','SE','TR','TW','US','ZA'

web_search_city
string | null

city name of the location used for searching the web
optional field

system_message
string | null

instructions for the AI behaviour
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?"}]

use_reasoning
boolean | null

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 1025
Note #2: if set to true, force_web_search must be set to false
Note #3: if set to true, the temperature and top_p cannot be used

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
