Anthropic API

The Anthropic API provides developers and enterprises with programmatic access to Claude, one of the world's most capable and safety-focused AI assistants. Whether you're building chatbots, analyzing documents, generating code, or creating entirely new AI-powered products, the API gives you the same Claude capabilities used by millions -- but integrated directly into your own applications.

What sets the Anthropic API apart is the combination of capability and safety. Claude models consistently score at the top of AI benchmarks while being designed from the ground up with safety in mind. The Constitutional AI training methodology means Claude is helpful, harmless, and honest. For enterprises, this translates to AI you can deploy with confidence, knowing it won't generate harmful content or leak sensitive information.

How It Works

Integrate the Anthropic API into your application using simple REST calls or official SDKs for Python and TypeScript. Send messages to Claude with your prompts, and receive responses in real-time or via streaming for longer outputs. The API supports multi-turn conversations with message history, system prompts for customizing Claude's behavior, and tool use for connecting Claude to external functions and data sources. Vision capabilities let you send images alongside text for multimodal understanding.
