Quick Start

use aigw_anthropic::{Client, Transport, TransportConfig, MessagesRequest, Message, MessageContent, Role};
use secrecy::SecretString;

# async fn example() -> Result<(), Box<dyn std::error::Error>> {
let transport = Transport::new(TransportConfig {
    api_key: SecretString::from("sk-ant-..."),
    ..Default::default()
})?;
let client = Client::new(transport)?;

let req = MessagesRequest::builder()
    .model("claude-sonnet-4-20250514")
    .messages(vec![Message {
        role: Role::User,
        content: MessageContent::Text("Hello, Claude!".into()),
    }])
    .max_tokens(1024)
    .build();

let resp = client.messages(&req).await?;
println!("{}", resp.body.id);
# Ok(())
# }
