cargo add openrouter-sdk

🚀 Quickstart: Build a Chatbot in 5 Minutes

use openrouter_sdk::{OpenRouterClient, ChatRequest, Message, Content};
use std::io::{self, Write};
use tokio::runtime::Runtime;

fn main() -> Result<(), Box<dyn std::error::Error>> {
    let rt = Runtime::new()?;
    let client = OpenRouterClient::new(
        std::env::var("OPENROUTER_API_KEY")?
    );

    println!("Chatbot ready! Type 'quit' to exit\n");
    
    let mut messages = vec![Message {
        role: "system".to_string(),
        content: Content::Text("You're a helpful Rust assistant".to_string()),
    }];

    loop {
        print!("You: ");
        io::stdout().flush()?;
        
        let mut input = String::new();
        io::stdin().read_line(&mut input)?;
        let input = input.trim();
        
        if input.eq_ignore_ascii_case("quit") {
            break;
        }

        messages.push(Message {
            role: "user".to_string(),
            content: Content::Text(input.to_string()),
        });

        let response = rt.block_on(client.chat(ChatRequest {
            model: "mistralai/mistral-7b-instruct".to_string(),
            messages: messages.clone(),
            temperature: Some(0.7),
            ..Default::default()
        }))?;

        if let Some(choice) = response.choices.first() {
            println!("Assistant: {}\n", choice.message.content);
            messages.push(choice.message.clone());
        }
    }
    Ok(())
}

while let Some(chunk) = stream.next().await {
    print!("{}", chunk?.text());
}

Image Analysis

Content::Multi(vec![
    ContentPart::text("What's in this image?"),
    ContentPart::image("https://example.com/cat.jpg")
])
