Request body

8 properties · 2 required · 2 $defs

property	type	description	constraints
prompt*	string	Prompt to be used for the chat completion
model*	string	Name of the model to use. Charged based on actual token usage.
reasoning	boolean	Should reasoning be the part of the final answer.	default: false
enable_web_search	boolean	Give the model access to real-time web information via OpenRouter's web search server tool. When enabled, the model decides when to search and may search multiple times per request. Search costs are charged in addition to token usage.	default: false
temperature	number	This setting influences the variety in the model's responses. Lower values lead to more predictable and typical responses, while higher values encourage more diverse and less common responses. At 0, the model always gives the same response for a given input.	0 ≤ n ≤ 2 · default: 1
web_search_options	WebSearchOptions	Options for the OpenRouter ``openrouter:web_search`` server tool.	nullable
system_prompt	string	System prompt to provide context or instructions to the model	nullable
max_tokens	integer	This sets the upper limit for the number of tokens the model can generate in response. It won't produce more than this limit. The maximum value is the context length minus the prompt length.	n ≥ 1 · nullable

WebSearchOptionsobject

Options for the OpenRouter ``openrouter:web_search`` server tool.

search_context_size	enum	How much content to retrieve per result. For Exa: low=5K, medium=15K, high=30K characters per result; when omitted, Exa picks adaptively (~2-4K per result). Ignored with native provider search. Overridden by max_characters when both are set.	low \| medium \| high · nullable
max_results	integer	Maximum results per search call (1-25). Applies to the Exa engine; ignored with native provider search. Defaults to 5.	1 ≤ n ≤ 25 · nullable
max_total_results	integer	Maximum total results across all search calls in a single request. Useful for controlling cost and context size in agentic loops.	n ≥ 1 · nullable
allowed_domains	string[]	Limit results to these domains. Supported by Exa and most native providers (not Google native search).	nullable
max_characters	integer	Exact maximum characters of content per result (1-100,000). Applies to the Exa engine; ignored with native provider search. Takes precedence over search_context_size when both are set.	1 ≤ n ≤ 100000 · nullable
engine	enum	Search engine to use. 'auto' uses native provider search when available and falls back to Exa. 'native' prefers the provider's built-in web search (OpenAI, Anthropic, Google, xAI, Perplexity), falling back to Exa for models without native support. 'exa' always…	auto \| native \| exa · default: "auto"
max_uses	integer	Maximum number of searches the model may perform in a single request. Once reached, further search calls return an error result instead of executing. With native provider search, forwarded only to Anthropic; other native providers ignore it.	n ≥ 1 · nullable
user_location	WebSearchUserLocation	Approximate user location to bias web search results geographically.	nullable
excluded_domains	string[]	Exclude results from these domains. Supported by Exa and some native providers (not OpenAI or Google native search).	nullable

WebSearchUserLocationobject

Approximate user location to bias web search results geographically.

country	string	Two-letter country code, e.g. 'US'.	nullable
region	string	Region or state, e.g. 'California'.	nullable
city	string	City name, e.g. 'San Francisco'.	nullable
type	const	Location type. Only 'approximate' is supported.	"approximate" · default: "approximate"
timezone	string	IANA timezone, e.g. 'America/Los_Angeles'.	nullable
