SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

REST APIs often suffer from unclear resource boundaries, inconsistent versioning, and vague error contracts. This skill provides a structured approach to designing durable, scalable APIs that are easy to evolve and document.

Core Features & Use Cases

  • Resources-first design: endpoints map to resources rather than actions
  • Clear versioning, pagination, and consistent status codes
  • OpenAPI documentation and predictable error responses

Quick Start

Describe a new API as resources, choose proper HTTP methods, and document the API with OpenAPI to ensure consistency across services.

FAQPage Schema
How do I design REST APIs with clear resources and consistent error contracts?

To design REST APIs effectively, map endpoints to resources rather than actions, apply clear versioning, and use consistent HTTP status codes to establish predictable error contracts for scalable services.

What is the best way to structure REST API pagination and endpoint conventions?

The best way to structure REST API pagination and endpoint conventions is by using a resources-first design approach, ensuring endpoints map directly to resources and applying consistent HTTP method usage across your services.

How do I document my REST API using OpenAPI specifications?

You document your REST API using OpenAPI specifications by modeling your API with clear resources, choosing proper HTTP methods, and generating documentation that ensures consistency across front-end and back-end services.

Does this REST API design approach work with Python FastAPI and Django?

Yes, this REST API design approach works with Python FastAPI and Django, as well as Node.js and front-end services, ensuring consistent method usage, status codes, and error contracts across different platforms.

Why do my REST API endpoints suffer from unclear resource boundaries and inconsistent versioning?

REST APIs suffer from unclear resource boundaries and inconsistent versioning when endpoints are modeled as actions rather than resources, lacking a structured approach to durable design and OpenAPI documentation.
