I spent 4 months building with Claude daily. Most developers treat it like a chatbot. It's not.
Claude gives you four paths: the Messages API for custom apps, the Agent SDK for agentic libraries, Claude Code for terminal coding, and claude.ai for browser work.
The difference between a productive setup and a frustrating one comes down to three files: your API key, CLAUDE.md, and your MCP config.
I wrote a setup guide covering everything from first API call to production workflows — verified against Anthropic's official March 2026 documentation.
What you'll learn:
- API key setup and your first call in 5 minutes
- Claude Code installation (one command, no IDE)
- CLAUDE.md: the config file that makes Claude follow YOUR rules
- MCP servers: connect GitHub, Slack, databases in one command
- 1M context window: standard on Opus 4.6 and Sonnet 4.6, no surcharge
- Official pricing: $3/$15 Sonnet, $5/$25 Opus, 90% savings with prompt caching
