Struct OpenRouterChatClient 

pub struct OpenRouterChatClient { /* private fields */ }

Process-wide OpenRouter chat client. Holds the model name so that callers only thread the per-item prompt/schema/input through Self::complete.

Implementations

impl OpenRouterChatClient

pub fn new( api_key: SecretBox<String>, model: String, timeout_secs: u64, ) -> Result<Self, AppError>

Builds a chat client bound to model, applying timeout_secs as the total per-request budget (wired from --openrouter-timeout). A value of 0 falls back to DEFAULT_TIMEOUT_SECS so a missing or zero flag never degrades into reqwest`’s immediate-timeout behaviour.

pub fn model(&self) -> &str

Returns the model bound to this client.

pub async fn complete( &self, system_prompt: &str, input_text: &str, schema_str: &str, max_tokens: Option<u32>, ) -> Result<(Value, f64, bool), AppError>

Runs a single structured-output completion.

schema_str is the JSON Schema (as a string) the model must honour under strict: true. When input_text is empty only the system message is sent. Returns (value, cost_usd, is_oauth) where value is the model output parsed as JSON, cost_usd is read from usage.cost (or 0.0 when absent), and is_oauth is always false because OpenRouter uses an API key, not OAuth.
