What is it?

Claude Cookbooks is a set of copy-able code snippets and guides for developers building with the Claude API. Most examples are Python Jupyter notebooks, and the concepts are presented so they can be adapted to other languages that can call the API.

The recipes are grouped by topic. Capability examples cover text classification, retrieval augmented generation, and summarization. Tool use examples show integrating Claude with external functions, such as a customer service agent, a calculator, and natural-language SQL queries. Further entries cover third-party integrations like Pinecone vector search, Wikipedia search, and Voyage AI embeddings.

Other notebooks address multimodal input for images, charts and forms, PDF uploads, JSON mode, moderation filters, prompt caching, automated evaluations, and sub-agent patterns that pair Haiku with Opus. A Claude API key is needed to run the examples.
