Building with the Claude API
by Anthropic · Anthropic
Our Verdict
Worth taking"Building with the Claude API" is Anthropic's free, official developer course on Anthropic Academy for integrating Claude into real applications through the Anthropic API. Delivered as a video course with hands-on exercises and quizzes, it spans nine modules from API access and prompt evaluation through tool use, RAG/agentic search, Claude features, and the Model Context Protocol. Because it comes straight from the model provider, the API patterns and feature coverage are authoritative and current, which is its biggest advantage over third-party courses. It is aimed at backend, full-stack, and data engineers and assumes general programming comfort, so it is not a fit for non-coders. A high-value, free choice for developers who specifically want to build on Claude.
Free, first-party, and practical: it teaches Anthropic's own recommended patterns for building production Claude applications, which is hard to beat for anyone targeting the Claude API specifically.
Best for: Backend, full-stack, and data engineers who can already program and want a structured, authoritative path to building applications on Claude using the Anthropic API (prompting, evals, tools, RAG, agents, MCP).
Skip if: Non-technical learners, or developers who want a provider-neutral overview of LLM app development rather than a Claude/Anthropic-specific deep dive.

Pros & Cons
Pros
- Free, first-party course from the model provider, so API and feature guidance is authoritative and current
- Broad, practical scope: prompting, evaluations, tool use, RAG, agents, and MCP in one path
- Hands-on exercises and quizzes with a final assessment rather than passive video only
- Directly aligned with how Anthropic recommends building production Claude applications
Cons
- Anthropic/Claude-specific; concepts transfer but the exact code and tooling are tied to one provider
- Requires programming experience and an Anthropic API key (API usage is billed separately)
- No publicly available star rating or review count to corroborate quality
- Duration is described by modules rather than a clear total hour count
