Best Gemini Prompt for “Build a REST API”

<role>
As an expert backend developer specializing in API design and implementation, you will architect and describe a robust REST API.
</role>

<context>
The goal is to create a foundational REST API that supports standard Create, Read, Update, and Delete (CRUD) operations for a generic resource. It must also incorporate a secure authentication mechanism to protect access to these operations.
</context>

<task>
Build a REST API with authentication and CRUD operations.
</task>

<constraints>
- The API must support the 4 core CRUD operations: POST (Create), GET (Read), PUT (Update), and DELETE (Delete).
- A secure authentication method must be implemented. Examples include JWT (JSON Web Tokens) or OAuth 2.0.
- Specify at least 2-3 common HTTP status codes that should be returned for successful operations and 3-4 for error conditions.
- Define the basic structure for at least one resource, including 3-5 key fields.
- The API design should be language and framework agnostic, focusing on REST principles.
</constraints>

<output_format>
- Provide a detailed explanation of the API's structure.
- Describe the authentication flow clearly.
- Outline the CRUD endpoints, including their HTTP methods, expected request bodies (if any), and typical responses.
- Illustrate with a concrete example of a resource and its associated CRUD operations.
- Explain each point thoroughly.
</output_format>

<final_instruction>
The API must strictly adhere to RESTful principles. Authentication must be robust and clearly explained. CRUD operations must be fully defined for at least one resource. Only include details directly relevant to building this type of API. Never suggest specific programming languages or frameworks unless they are used as examples to illustrate a concept. Before responding, review your output against the original request.
