Claude Quickstarts
Anthropic's official Claude API quickstarts — agentic customer service, RAG, skills, and more, in working notebooks.
Anthropic's official quickstart repository covers the most common Claude API patterns in Python and TypeScript: agentic customer service, retrieval-augmented generation, skills, and tool use. Each example is a runnable notebook with a README walking through the architecture.
What it does
- Anthropic's official quickstarts — agentic customer service, RAG, skills, computer use, and tool-calling, all as runnable notebooks
- Each README walks through the architecture
- The fastest sanctioned path from idea to working Claude API code
When to use it
Start here when building your first Claude API app: pick the quickstart closest to your use case, run the notebook, then adapt it to your data.
Getting started
git clone https://github.com/anthropics/claude-quickstarts Each subdirectory has its own setup instructions and API-key env var.
Things to know
Quickstarts are teaching examples, not production templates — they intentionally skip auth, rate-limit, and observability concerns. Treat them as scaffolding to harden.
