Parameters
| Parameter | Type | Required | Default | Description |
|---|---|---|---|---|
temperature | number | no | 0.2 | Sampling temperature. 0 = deterministic, 2 = maximum randomness. · Range: 0 – 2 |
top_p | number | no | 0.9 | Nucleus sampling probability mass. Lower = more focused. · Range: 0 – 1 |
max_tokens | number | no | 4096 | Maximum tokens in the response. · Range: 1 – 32768 |
search_context_size | enum | no | "medium" | Higher context gives better answers but increases the base fee per request. · Allowed: low, medium, high |

search_domain_filter | string | no | - | Comma-separated domains. Prefix with ’-’ to exclude. Max 20. |
search_language_filter | string | no | - | Comma-separated ISO 639-1 codes (2 letters). Max 10. |
search_after_date | string | no | - | Use YYYY-MM-DD. Only include sources after this date. |
search_before_date | string | no | - | Use YYYY-MM-DD. Only include sources before this date. |
search_recency_filter | enum | no | "none" | Relative time filter. Cannot be combined with specific dates. · Allowed: none, hour, day, week, month, year |
last_updated_after_filter | string | no | - | Use YYYY-MM-DD. Only include sources after this date. |
last_updated_before_filter | string | no | - | Use YYYY-MM-DD. Only include sources before this date. |

region | string | no | - | State or province name for location bias. |
city | string | no | - | City name for location bias. |
latitude | number | no | - | Latitude for location bias, in decimal degrees. |
longitude | number | no | - | Longitude for location bias, in decimal degrees. |
return_images | boolean | no | false | Include relevant images alongside the search results. |
image_domain_filter | string | no | - | Comma-separated domains for image results. Prefix with ’-’ to exclude. Max 10. |

return_videos | boolean | no | false | Include relevant videos alongside the search results. |
disable_formatting | boolean | no | false | Skip the EmpirioLabs Markdown formatting (citation [N] rewriting + References block + Images / Videos blocks). The raw upstream answer with plain [N] citations is returned; structured search_results / citations still pass through where Perplexity emits them. |
Notes
