SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

The API design discipline helps teams create clear, consistent REST interfaces, robust error handling, and secure access patterns to reduce integration friction and miscommunication between services.

Core Features & Use Cases

  • REST API best practices, OpenAPI/Swagger patterns, authentication, and error response formats.
  • Guidance on versioning, error schema, and security considerations for public and private services.
  • Use Case: Design a new service with predictable contracts to accelerate onboarding of frontend apps and partner integrations.

Quick Start

Draft the initial OpenAPI spec for a new resource with basic CRUD endpoints and a JWT-based authentication scheme.

Frequently Asked Questions about API Design

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I design a REST API with OpenAPI to ensure stable interfaces for microservices?▼

Design robust REST APIs with OpenAPI by applying consistent schemas, versioning strategies, and robust error handling to ensure stable interfaces for microservice ecosystems and partner integrations.

How do I structure JWT authentication in an OpenAPI specification?▼

Structure JWT authentication in an OpenAPI specification by defining token-based security schemes, ensuring your OpenAPI documentation accurately reflects the required authentication patterns for accessing protected resources.

What is the best way to handle REST API versioning and error schemas?▼

Handle REST API versioning and error schemas by establishing consistent error response formats and versioning strategies, reducing integration friction and miscommunication between frontend apps and services.

Does this REST API design approach work for both public and private services?▼

Yes, this REST API design approach works for both public and private services, providing guidance on security considerations, error schemas, and versioning to ensure predictable contracts across different service types.

How do I draft an initial OpenAPI spec for a new resource with CRUD endpoints?▼

Draft an initial OpenAPI spec for a new resource by defining basic CRUD endpoints alongside a JWT-based authentication scheme, accelerating the onboarding of frontend apps and partner integrations with predictable contracts.

Why does REST API design fragility cause integration friction between services?▼

REST API design fragility causes integration friction due to inconsistent interfaces and unclear error handling, which you can solve by applying consistent OpenAPI schemas, versioning strategies, and secure access patterns.
