Audit how ChatGPT, Claude, Gemini or Perplexity answer a prompt about a brand, product or category, for AI visibility, answer engine optimization (AEO) and generative engine optimization (GEO): returns the answer, the sources it cited and the brands it names. Only for measuring AI answers, never as a general assistant to draft content or answer the user: each call is billed to the user's DataForSEO balance plus the model provider's token cost.

## Inputs

| Field               | Type                       | Required | Default    | Description                                                                                                                                                                                                                                                                                                                  |
| ------------------- | -------------------------- | -------- | ---------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `provider`          | string or SelectableOption | No       | `chat_gpt` | AI provider to ask: 'chat\_gpt' (OpenAI, default), 'claude' (Anthropic), 'gemini' (Google) or 'perplexity'.                                                                                                                                                                                                                  |
| `model`             | string                     | No       | -          | Model name as listed by dataforseo\_list\_llm\_models, e.g. gpt-4.1-mini, gpt-5.5, claude-sonnet-5, gemini-2.5-flash, sonar-pro. Leave empty for the provider default (gpt-4.1-mini, claude-haiku-4-5, gemini-2.5-flash, sonar). Reasoning models such as the gpt-5 family cost more and cannot be forced to search the web. |
| `prompt`            | string                     | Yes      | -          | The question or task to send, e.g. 'What are the best project management tools for agencies?'                                                                                                                                                                                                                                |
| `system_message`    | string                     | No       | -          | Optional instructions that set the role, tone or format of the answer.                                                                                                                                                                                                                                                       |
| `web_search`        | string or SelectableOption | No       | `auto`     | 'auto' (default) lets the model decide whether to search the web, 'always' forces a web search so the answer cites live sources (chat\_gpt non-reasoning models such as gpt-4.1-mini, and claude), 'off' answers from training data only. Perplexity always searches the web.                                                |
| `country`           | string or SelectableOption | No       | -          | Two-letter country code (US, GB, DE...) used to localise the web search; a DataForSEO country location code such as 2840 also works. Not supported by gemini. Leave empty for the provider default.                                                                                                                          |
| `max_output_tokens` | integer                    | No       | -          | Maximum length of the answer in tokens (16 to 4096). Leave empty for the model default. Reasoning models such as the gpt-5 family and the o-series do not accept it.                                                                                                                                                         |
| `temperature`       | number                     | No       | -          | Randomness of the answer from 0 (deterministic) to 2 (creative). Leave empty for the provider default.                                                                                                                                                                                                                       |
