Gemini API with AI Studio: Build a Small Tested App
Product details checked: 4 October 2026

Prompt
Design a server-side Gemini action-list prototype for public notes. Define a schema with task, owner, and uncertainty. Include validation, key handling, and tests. Use a currently documented model ID and do not invent SDK methods.

Review
- No API secret reaches the browser.
- Missing owners remain missing.
- Failure produces a visible recoverable state.

Practice
Create three fictional notes: a complete action, an action without an owner, and contradictory deadlines. Define expected structured outputs before calling the API. Simulate a timeout and inspect the frontend error state. Check browser resources to ensure the secret is absent. Record sample usage before increasing traffic.
