No-Code API Mastery: The "Master Prompt" I Use to Build Apps with Claude Code

Build professional apps with real-world data in under 10 minutes. In this video, I’m showing you the "Master Prompt" technique—the exact framework I use as a technology professional to bridge the gap from Idea to Execution using Claude Code.

We aren't just writing code; we are architecting a solution. You’ll watch me build a fully functional Photo Finder app using the Unsplash API without writing a single line of manual code.

What you will learn in this session:
✅ The Master Prompt: My 4-step framework for perfect API integration.
✅ API Keys for No-Coders: How to safely connect Unsplash to your local environment.
✅ Live Execution: Watching the Claude Code terminal build and link your files.
✅ Iteration: How to "talk" to the AI to refine your UI and add professional features.

If you’ve been stuck building "static" pages, this is your level-up to dynamic, API applications.

🚀 The "Master Prompt" Template
Copy and paste the prompt below into Claude Code to build your own API-driven applications. Just replace the bracketed information with your specific project details.

--Master Prompt Starts--
The Prompt:
Role: Act as a Senior Full-Stack Web Developer.
Task: Build a (Type of App, e.g., Photo Gallery) that connects to the (Name of API, e.g., Unsplash) API.
Context: I have an API Access Key: (Paste your Key here or tell Claude to ask for it).
Goal: Allow users to search for (Topic) and display (Number) results.

Requirements:
Architecture: Use a clean multi-file structure (index.html, style.css, script.js).
UI/UX: Design a minimalist, mobile-responsive layout. Use a (Dark/Light) theme.
Functionality:
Implement a search bar and a submit button.
Display results in a (Grid/List) layout.
Add a loading state while fetching data.

Safety: Do not hardcode the API key if possible; use a separate config or environment variable.
Execution: Initialize the project and build the core functionality now.

💡 How to use this template:
Identify your API: Whether it's Unsplash, OpenWeather, or Spotify.
Fill in the (Brackets): Tailor the design and features to your specific idea
Execute: Paste the entire block into your Claude Code terminal and watch it build.
