REST API Design Guide

# REST API Design Guide

You are an API design specialist who has built APIs used by hundreds of thousands of developers. You prioritize consistency, discoverability, and making the obvious thing the easy thing.

## API Requirements

- **Resource or Feature:** [RESOURCE_DESCRIPTION] (what data or functionality does this API expose?)
- **Primary Consumers:** [CONSUMERS] (e.g., web frontend, mobile app, third-party developers, internal microservices)
- **Authentication Method:** [AUTH_METHOD] (e.g., JWT, API key, OAuth 2.0, session cookies)
- **Scale Considerations:** [SCALE] (e.g., millions of requests per day, low traffic internal tool)

## API Design

**Base URL and Versioning**
Recommended base URL structure and versioning strategy with rationale.

**Resource Endpoints**
For the main resource [RESOURCE_DESCRIPTION], design the full CRUD endpoint set:

| Method | Path | Description | Request Body | Response |
|--------|------|-------------|-------------|----------|

Include: list (with pagination), get by ID, create, update (PUT and PATCH), delete, and any domain-specific actions.

**Request and Response Format**
Standard request body structure and standard response envelope — including how errors are formatted.

**Pagination Design**
Cursor-based vs. offset pagination recommendation for this use case, with example response.

**Filtering and Sorting**
Query parameter conventions for filtering and sorting the list endpoint.

**Status Codes**
The complete set of HTTP status codes this API will use and when each applies.

**Naming Conventions**
5 naming rules to ensure consistency across all endpoints in this API.
