What problem does it solve?
It helps you build reliable applications with the Claude API and Anthropic SDKs without having to piece together model selection, streaming, tool use, and request formatting on your own.
Core Features & Use Cases
- Language-specific integration guidance: Covers Python, TypeScript, Java, Go, Ruby, C#, PHP, and raw HTTP so you can start in the stack you already use.
- Production API workflows: Shows how to handle chat, streaming, tool calling, batch processing, file uploads, prompt caching, structured outputs, thinking, and compaction.
- Developer guardrails: Explains exact model IDs, error handling patterns, and the right SDK types and request shapes to avoid common integration mistakes.
- Use cases: Build chat assistants, agentic workflows, document analysis pipelines, cached multi-turn conversations, and high-volume batch jobs.
Quick Start
Open the Claude API guide for your programming language and follow its first message example to send a prompt with the correct model and max token settings.
