Hanzo AI is OpenAI-compatible, so existing Rust code works with zero refactoring. We deeply appreciate the Rust Foundation team for building and maintaining this open-source project.

Cargo.toml

[dependencies]
async-openai = "0.26"
tokio = { version = "1", features = ["full"] }

async-openai

rust
use async_openai::{config::OpenAIConfig, Client, types::*};

#[tokio::main]
async fn main() {
    let config = OpenAIConfig::new()
        .with_api_base("https://api.hanzo.ai/v1")
        .with_api_key(std::env::var("HANZO_API_KEY").unwrap());

    let client = Client::with_config(config);

    let request = CreateChatCompletionRequestArgs::default()
        .model("zen4-pro")
        .messages([ChatCompletionRequestUserMessageArgs::default()
            .content("Hello from Rust!")
            .build()
            .unwrap()
            .into()])
        .build()
        .unwrap();

    let response = client.chat().create(request).await.unwrap();
    println!("{}", response.choices[0].message.content.as_ref().unwrap());
}

reqwest raw HTTP

rust
use reqwest::Client;
use serde_json::json;

#[tokio::main]
async fn main() {
    let client = Client::new();
    let resp = client
        .post("https://api.hanzo.ai/v1/chat/completions")
        .bearer_auth(std::env::var("HANZO_API_KEY").unwrap())
        .json(&json!({
            "model": "zen4-pro",
            "messages": [{"role": "user", "content": "Hello!"}]
        }))
        .send()
        .await
        .unwrap();
    println!("{}", resp.text().await.unwrap());
}
