SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

REST API design and development can be error-prone without a structured approach. This skill provides expert guidance on HTTP semantics, resource modeling, versioning, error handling, pagination, and OpenAPI documentation to ensure scalable, maintainable APIs across teams.

Core Features & Use Cases

  • Endpoint design: create noun-based resources, consistent hierarchies, and clear versioning strategies.
  • HTTP semantics and error handling: apply correct methods, status codes, and a standard error envelope for client resilience.
  • Documentation and governance: generate and maintain OpenAPI specs, with deprecation plans and change previews for new versions.
  • Use Case: design a new service's API surface, then align routes, errors, and docs for stakeholders.

Quick Start

Provide a baseline REST API design for a new service by outlining endpoints, versioning strategy, error handling, and OpenAPI documentation.

FAQPage Schema
How do I design a REST API with correct HTTP semantics and status codes?

Designing a REST API with correct HTTP semantics involves mapping noun-based resources to appropriate methods and status codes. This skill enforces practical constraints like versioned routes, correct status codes, and consistent error formats to ensure scalable, maintainable services across teams.

What is the best way to structure REST API versioning and deprecation?

Structuring REST API versioning uses versioned routes with clear deprecation plans and change previews. This skill applies practical versioning strategies to endpoint design, ensuring smooth transitions and governance across multiple services.

How do I generate OpenAPI documentation for my REST API endpoints?

To generate OpenAPI documentation for REST API endpoints, create and maintain specs that align routes, errors, and docs for stakeholders. This skill handles OpenAPI spec generation alongside endpoint design, versioning, and error handling to keep documentation accurate and consistent.

Why do I need a standard error envelope for REST API error handling?

You need a standard error envelope for REST API error handling to build client resilience and maintain consistency. This skill applies a standard error format alongside correct status codes and HTTP semantics to ensure clients can parse and handle failures predictably.

Can I use this REST API design approach for services requiring pagination?

Yes, this REST API design approach works for services requiring pagination. This skill covers endpoint design, HTTP semantics, versioning, error handling, and pagination to create robust REST API designs for scalable services across multiple use cases.
