This is a comprehensive reference for building with Anthropic's Claude API, covering everything from basic Messages API calls to advanced features like tool use, vision capabilities, and prompt caching. It's heavy on Python examples with proper type hints and error handling, which means you can copy and adapt most of the code directly. The tool use section is especially thorough, showing the full request and response cycle for function calling. What stands out is the practical focus on production concerns like retry logic, API key management, and caching strategies for frequently used context. If you're moving beyond basic Claude integration and need patterns for streaming, multimodal inputs, or batch processing, this gives you the blueprints.
