Crate anthropic_api

Anthropic Rust SDK

An unofficial Rust library for interacting with the Anthropic API. This library provides an asynchronous interface to Anthropic’s services, allowing Rust developers to seamlessly integrate Anthropic’s AI capabilities into their applications.

Features

• Asynchronous API Requests: Leverage Rust’s async capabilities for efficient API interactions
• Message API: Send and receive messages, similar to chat-based interactions
• Tool Use: Integrate external tools that the AI can call during responses
• Streaming Responses: Receive real-time streamed responses from the API

Basic Usage

use anthropic_api::{messages::*, Credentials};

#[tokio::main]
async fn main() {
    // Load credentials from the environment
    let credentials = Credentials::from_env();

    // Create a message
    let messages = vec![Message {
        role: MessageRole::User,
        content: MessageContent::Text("Hello, Claude!".to_string()),
    }];

    // Send the message to the Anthropic API
    let response = MessagesBuilder::builder("claude-3-7-sonnet-20250219", messages.clone(), 1024)
        .credentials(credentials.clone())
        .create()
        .await
        .unwrap();

    // Print the assistant's response
    if let Some(ResponseContentBlock::Text { text }) = response.content.first() {
        println!("Assistant: {}", text.trim());
    }
}
