Claude API and Claude Code guides for business automation
This is my working map of Claude for business automation. It collects what I have written on the Claude API and Claude Code, from first setup through real builds to choosing a model and keeping the bill down.
Most of these are notes from things I built, and the model posts are my read on what each release changes for automation. If you are new, start with the first group and read down. If you already know the basics, jump to the group that matches your question.
