Crate anthropic_async 

anthropic-async

A production-ready Anthropic API client for Rust with prompt caching support.

Quick Start

use anthropic_async::{Client, types::{content::*, messages::*}};

let client = Client::new();

let req = MessagesCreateRequest {
    model: "claude-3-5-sonnet".into(),
    max_tokens: 100,
    messages: vec![MessageParam {
        role: MessageRole::User,
        content: "Hello!".into(),
    }],
    system: None,
    temperature: None,
    stop_sequences: None,
    top_p: None,
    top_k: None,
    metadata: None,
    tools: None,
    tool_choice: None,
    stream: None,
    output_format: None,
};

let response = client.messages().create(req).await?;

Authentication

The client supports API key and bearer token authentication. See AnthropicConfig for configuration options.

Prompt Caching

Use CacheControl to cache prompts and reduce costs.
