An Anthropic SDK for Java that enables Java applications to seamlessly integrate with the Claude API. This SDK simplifies the process for Java developers to leverage Anthropic's advanced AI models, offering a direct interface for message creation and interaction.

How It Works

The SDK provides a Java client (AnthropicClient) built on OkHttp, abstracting the complexities of direct API calls. Developers can configure the client using environment variables, such as ANTHROPIC_API_KEY, and then instantiate message creation parameters (MessageCreateParams) to interact with specific Claude models. The core approach focuses on providing a type-safe and idiomatic Java API for accessing Claude's capabilities.

Quick Start & Requirements

• Installation:
  • Gradle: implementation("com.anthropic:anthropic-java:2.16.0")
  • Maven:

    <dependency>
      <groupId>com.anthropic</groupId>
      <artifactId>anthropic-java</artifactId>
      <version>2.16.0</version>
    </dependency>
    

• Prerequisites: Java 8+. The ANTHROPIC_API_KEY environment variable must be set for authentication.
• Documentation: Full documentation is available at platform.claude.com/docs/en/api/sdks/java.
