Description

A step-by-step guide to the Claude API: costs first, then the building blocks, then one small working project with Claude Code writing the code.

Your first working Claude API project, step by step.

A plain-language guide to putting Claude inside your own tool or workflow: costs first, then the building blocks, then a working product with Claude Code doing the code.

Claude API: who it’s for

  • You’ve done the same job in a Claude chat fifty times (summarise this, sort these, draft that) and you want it to run by itself.
  • You opened the developer docs, saw a wall of code and words like endpoint and token, and closed the tab.
  • Your real worry isn’t the code. It’s the bill: what if a mistake runs up charges while you sleep?
